More additions to come...
This compendium will work hand-in-hand with Constantius's thread general priest items will remain there primarily. Disc specific items, additionsâ€¦ etc will be here. This is a compilation of data contributed on threads such as the "WotLK Healing Compendium v3.0..." and the previous Discipline Priest compendium thread. For specific information about Shadow specs please refer to there latest threads for the most current information.
Disclaimer: This thread and this post will evolve with current theorycraft. While the data presented here should be accurate it is advisable that you use it with some discretion. Errors, omissions, and significant additions should be PM'd to me to ensure I update the main body of this post. Remember Discipline has only been a viable PvE healing spec for a short time and doesn't have a long theorycraft history from which to draw.
A short list of terms that will be used in this thread and in the dicussion following.
BT - Borrowed Time
DA - Divine Aegis
WS - Weakened Soul
oo5sr - Out of 5 second rule
i5sr - Inside of 5 second rule
PoM - Prayer of Mending
PoH - Prayer of Healing
HpM - Healing per Mana, a measurement of efficiency
HpS - Healing per Second, a measurement of throughput
MpS - Mitigation per Second, a measurement of throughput
I. Spec's & Talents
A. Disc Specs
There are currently two baseline methods for talent spec as a Discipline priest. There have been several more exotic multi-tree specâ€™s proposed though as of yet the viability of them has not been demonstrated well enough to be included. The primary difference between the two base specâ€™s is the Holy talent Improved Healing. Based on the depth into the Holy tree to acquire it (IH) some items in the Disc tree have to be sacrificed.
In either of the following specs the focus is single target healing through the use of both mitigation and direct healing. Raid healing support can be accomplished through PW:S, BTâ€™d PoH, PoM, and quick reactive heals.
57/13/0, this spec has all of the Discipline tools available. The remaining point is discretionary.
53/18/0. This spec trades 4 points in Disc for Improved Healing. In Disc I would sacrifice and go with 1/2 Grace, 1/3 Improved Flash Heal, and without Power Infusion. The 2 points in Spell Warding can be spent at your discretion.
Q: What are the most important talents for Discipline?
A: The majority of the PvE talents in the Discipline tree are necessary to reach full potential. The most important talents are Penance, Divine Aegis, Focused Power, and Aspiration. There are quite a few other good talents though I would not sacrifice these from any build.
Q: How valuable is Improved Healing?
A: This is an efficiency talent and only has value so far as your difficulty with mana management.
Penance is 618 x 15% = 92.7 mana saved if used on CD. It is worthâ€¦
~72.42 mp5 (w/Glyph)
~57.94 mp5 (w/out Glyph)
Divine Hymn is 2434 x 15% = 365 mana saved. Because of the long CD on this ability it isnâ€™t a significant amount over the duration of the fight, the longer the fight the less mp5 contribution.
Greater Heal is 1236 x 15% = 185.4 mana saved per cast. This is a decent savings and you can calculate the equivalent mp5 you would receive based on the number of casts of your play style. You can approximate it at 15 mp5 for each cast of GH over a one minute period.
Q: Is 1/2 Grace superior to 2/2 Grace?
A: It provides the chance that if you FH/GH off your primary healing assignment that the Grace stack does not transition with a single heal. If you Penance off target there is a 1/8 chance it doesnâ€™t transition. For this reason some people consider taking 1/2 superior though this would be the incorrect reason for it to be superior.
Re-stacking Grace on the primary target comes as a cost. Rember Penance counts as 3 healsâ€¦ This section has been reworked to better display the cost of going down to 1/2 Grace.
1/2 Grace â€“ It will take 6 direct heals to ensure a triple stack of Grace at greater than 98%. The average cost to Healing/Mitigation provided during this time is 6.5% and it could cost as much as 8.3%. If there is some bad RNG it could take longer than 6 heals which will increase the average over a 7% loss.
2/2 Grace â€“ It will take 3 direct heals to re-stack Grace. The total loss of healing on the target is the equivalent of 4.7% of the total Healing/Mitigation during the process of restacking when compared to 1/2.
While maintaining Grace on the primary target is great, the cost that is incurred if it does move with 1/2 Grace is quite a bit higher than if you have 2/2 Grace. If you donâ€™t off heal it is a viable option because it will not take long to stack it and is not likely to fall off. Though it is not better because it give the possibility of the stack not moving and the point shouldnâ€™t be dropped for this reason. It is actually overall better to keep the second point if you will off-heal because the penalty is less. You could drop the point in the process of pickup Improved Healing if you plan to not off-heal and risk the stack to often.
II. Mana Regeneration
A. Base Regen
As a traditionally "spirit based" mana regeneration class. The level 80 version of the mana regeneration from Int and Spi now follow the following formula's:
oo5sr = 0.016725 * Spirit * SqRt(Intellect)
i5sr = oo5sr * .17/.33/.50 (Based on the points in meditation. 3/3 Meditation is standard in all specs.)
This portion of the mana regeneration model is the only reason for Discipline to utilize Spirit at all.
Rapture had a major overhaul with the 3.1 release. It was quite imbalanced in its previous incarnation, though the current mechanic has some issues. Rapture provides 1.5/2.0/2.5% of total mana when a PW:S is completely consumed or dispelled and can only occur once per 12 seconds.
The maximum regeneration from Rapture is:
(Mana Pool) x Return% / 12 * 5 = X mp5
The maximal return is unrealistic and should instead be evaluated based on the amount per proc and the proc rate received. Instead you find that:
(Mana Pool) x Return% / 12 = X mp5 per proc, where the proc rate is from 0-5 procâ€™s/min.
21568 x 2.5% / 12 = 44.93 mp5/proc... The PTR proc rate data I was running was ~3.4 proc/min. So this would indicate ~152.8 mp5.
There needs to be more data collected and theorycraft analysis on the proc rate. The proc rate depends on multitude of factors. For a single target the proc rate is maximally 4/min based on the WS debuff. How close to this can be achieved is based on damage income and pattern, target avoidance, target mitigation..etc calculating an average â€œtime to consumptionâ€â€¦ Optimally a time to consumption of less than 3 seconds yields 4 proc/min.
1 Int = ~0.1538 mp5, maximally
1 Int = ~0.1045 mp5, 3.4proc/min
The mechanic behind Rapture indicates that PW:S should be used with regularity on any target that will benefit from being shielded and provides the potential or guarantee of the shield being completely consumed.
Replenishment is a talent available to a multitude of class/specs... The buff provides a 15 second buff on up to 10 people that restores 0.25% of total mana every second for the duration of the buff. Mental Strength couples well with Replenishment in a raid/group environment for Discipline.
1199 Int provides 17705 mana. That 17705 mana at 0.25% is 44.2625 mana per second or ~221 mp5. Based on the 221 mp5 @ 1199 Int you find that -
1 Int = ~0.18458 mp5 (not accounting Blessing of Kings or Mental Strength)
D. Mana Pool
The larger the mana pool the better the longevity over the course of the fight. This equates to mana regen based on the fight duration.
Mana Pool / Duration * 5 = X mp5, working with a 5 min fight duration at the previously demonstrated Int amount it works out too.
17705 / 300 * 5 = ~295.08 mp5
1 Int = ~0.2461 mp5 (not accounting Blessing of Kings or Mental Strength)
E. Spirit vs. mp5
The more Int the more valuable Spi becomes, though without a secondary benefit of having Spi it is a fairly weak stat for Disc. It takes approximately 3 Spi to equal 1 mp5.
Giving the opportunity Disc should choose quality mp5 gear over spirit.
III. Raiding as Discipline
Discipline can be used very dynamically in a raid environment much like Holy was in BC and before 3.1 released. While all healers should be less concerned with meters and more about keeping people alive, as Disc you need to be even less reliant on current meters. The majority of Disc contribution is not visible on most meters (see Add-On section).
A. Tank Healing
The primary tools as a tank healer are Penance, Flash Heal, PW:S, PoM, and occasionally Greater Heal.
Q: Should PW:S be saved for â€œburstâ€ healing on the tank?
A: In most cases it is far and away more important to maintain the Weakened Soul debuff on the tank to ensure the highest crit rate possible. There are occasions where it may be necessary to line-up the application of PW:S with large strikes on the tank. Even at these times the cast shouldnâ€™t be delayed unless absolutely required for tank survival, instead the order of casting should align such that the PW:S lands prior to the big strike as often as possible. Penance alone is significant â€œburstâ€ and provides enough for most encounters.
B. Raid Healing Support
The new talent Soul Warding and the change to PoH group targeting provide significant improvement to Disc raid healing. The large amount of predictable raid damage in Ulduar provides ample opportunity for Disc to pre-shield to help create time for the other raid healers. Shielding of raid members provides additional BT casts on either the tank or for reactive raid healing and works well with the new Rapture mechanic.
Disc is NOT an optimal choice for raid healing. It is however the only choice for raid mitigation so switching specs isn't optimal. Weaving PW:S onto raid members, well timed PoH, and PoM are more than enough to allow Disc to fill a niche in any raid. All this can be done while healing the MT if necessary.
C. Specific Fight Information
This section will be updated with some best practices or helpful play style information that applies to specific fights, damage patterns â€¦etc. <Still In-Progress>
IV. Healer Interaction
Q: Disc and Holy Priests working together reducing PoM performance due to PW:S?
A: Discipline and Holy priests complete each other very well in a raid situation. Shielded targets will delay the bouncing of PoM though it is not enough to greatly reduce the healing of the Holy priests stronger PoM. The goal is to keep the raid alive not to â€œwin the metersâ€. The use of PW:S provides a great amount of survivability and even if it slows a PoM bounces.
A. Stat Weighting
The stat ratings presented are generated from the Disc Spreadsheet that will be attached in a later section.
- Intelligence - 0.16
- Spell Power - 1.0
- Crit Rating - 0.48
- Haste Rating - 0.59
Discipline through use of BT and with Enlightenment has a lower need for gearing to haste. It is valuable for total output at the above stat weighting up to the point you reach the "soft cap" of a total haste of 50%. At that point the GCD is 1 second and more haste impacts less of the Disc arsenal of tools. This point varies based on the buffs available and should be individually calculated.
- 1 Intelligence = 0.74 mp5
- 1 Spirit - 0.33 mp5
For those that utilize a combined stat weighting you can use the following. Though I usually work with them seperately in order to better balance my gear selection. The longevity stats are important to balance mana burn and mana gain for your playstyle, mana beyond that point is unnecessary.
Combined stats... Using a 60/40 split for throughput vs. longevity.
- Intelligence - 0.65
- Spirit - 0.22
- Haste Rating - 0.59
- Crit Ratng - 0.48
- Spell Power - 1.0
- Mp5 - 0.67
When gearing you need to consider what stats you are short on at the current time. This means looking at do you need more mana regen or greater throughput? Be sure to consider which gems and enchants will couple with the piece.
Discipline priests should always consider gear with Mp5 in place of Spirit. For regen Intellect is ultimately the best stat because it has dual value through conversion to crit at a rate of 132:1. Once you consider Blessing of Kings and Mental Strength 1 Int very nearly compares to 1 Mp5.
*The following post will present the current BiS "known" options.
The most valuable gems are... There are more obviously, though these are the ones to consider for Discipline gearing. If gearing for Holy/Disc combined refer to the WotLK Healing Compendium to get help select the best overal gem.
Primary choices... Selection based on whether you need more regen or more throughput.
- The highest regen meta available until extreme levels of Int. A 45-second ICD proc that restores 600 mana and 21 intellect.
- A good choice for mixed throughput and longevity.
After additionally theorycrafting it is possible this could be a contender for the best throughput meta.
- Possible contender with ESD for output.
Currently the enchanting of either Disc or Holy is fairly similar. Reference the WotLK Healing Compendium v3.1 for specific enchants. Discipline can generally focus on the higher throughput enchants as regeneration is less of an issue generally. In some cases such as Boots taking a Spirit enchant may be the best option even though it wouldn't be the optimal choice with different options available.
Glyph of Penance
Glyph of Power Word: Shield
Glyph of Flash Heal
Glyph of Prayer of Healing
Of the options for the remaining 2 Major glyphs dropping FH is an option if you don't need additional efficiency in order to keep glyphs that improve throughput. If efficiency of FH is something you need then it would probably be PoH that would be on the chopping block.
There are a few decent minor glyphs you can choose between.
Glyph of Fading - Good savings on mana.
Glyph of Levitate - Saves from purchasing or farming spell casting materials. Kind of handy.
Glyph of Shadowfiend - With improved Shadow Fiend survivability this glyph may be outdated.
Glyph of Shadow Protection - Not necessary but could be the replacement for Shadowfiend Glyph.
The RecountGuessedAbsorb addition to Recount made available by Elisa, is proving to be a viable current option for giving general information for mitigation/absorption provided. This can be used by raid leaders and healers looking for more real-time informaiton about the contribution of Disc priests to the larger raid healing environment.
Disc Priest Spreadsheet this link will be updated as I continue to evolve this information source.
This is the first ready for public consumption copy of my spreadsheet. I am still working on adding more things to this spreadsheet. It is not complete yet but is in a workable form that should be usable by most people, you will notice some areas of the sheet are blank because they have not been ported over from less 'pretty' spreadsheet.
Please do NOT clutter this thread with discussion of the spreadsheet. If there are items that you require assistance with, improvements that you think should be made, or corrections to any mistakes that may be present please PM me. If there is sufficient need for discussion it may warrant another thread but at this time I would like to keep it in PM.
PM me any specific information not listed you would like in the compendium, or sections that you think would be valuable.
