Yes, i hope that next modification will not be simply to remove them....

Probably our main problem was the amount of mana consumption while using SS.

To reduce cost of spell under SS proc would be better.

Wait & see !

***************

Now, i answer to your post of friday , Havroc.

1/ We agree 600 mastery points are 2.5%

2/

Please don't use the old notation of base + %spellpower. It is frought with errors. Spellpower has been normalised for all spells so it always adds the same % of the base value across the board.

OK, usualy i do not take this notation.(i took it to be more understandable)

Notation that i take is near from you but results are same at the end.

This notation comes from

Average Heal = base Heal + CoefSP * SP = Base Heal * ( 1 + 1%* SP* CoefSP/Base Heal)

becomes

**Average Heal = Base Heal * ( 1 + 1%* SP / ScoreSP)**

with ScoreSP = Base Heal/CoefSP = 19428/187.1%/100 ~ 103.838Basicaly k universal constant that you use is not universal but only applied on PWS.

It is the same factor that i have defined in my formula :

k = 1%/ScoreSP = 0.0000963043....

You have found k=0.000096564716 which is probably not correct if Wowhead database is up to date.

But i found new evolution on WoWdb (

Power Word: Shield - Baseline - Priest - Class Abilities - Spells - WowDB)

where PWS seems to have a different base value depending on Disc spec.

I have checked IG the correct value and i have confirmed that WoWHead was correct.

PWS = 61427 on tooltip and it is the value shown when casted with SP=12695 and mastery= 5342 points = 0.422583 (42.26% on tooltip)

Verification by formula gives the same result = PWS = 19428* ( 1 + 1%* 12695 / 103.838)*(1 + 42.2583%) = 61427.6 which matchs perfectly well.

Anyway to take k=0.000096564716 or 0.0000963043 will not have a real influence on the result.

And this is not on this value that we have discussed.

I come back on your formula because i think you made a mistake in buff behavior if "spellpower" = total fully buffed spellpower

You wrote

%increase_SP = 100*(Int*B*k)/(1+spellpower*k)

My formula is

%increase_SP = 100*(Int*B)/(100*ScoreSP+spellpower)

Which are exactly the same with k = 1%/ScoreSP

So on this point, we are ok together.

The problem for me is the definition of B

you miss the +10% of raid spell buff (given by sham/warlock/mage).

So you miss a 10% of improvement also done by the +100 INT

so in your example at 25000 spellpower 100 intellect adds

%increase_SP = 0.2826152081*B which is the same result as you if i take ScoreSP~100 as you have tacken k~0.0001.

for reference, you found 100*B*0.0001/(1+2.5)*100 = 0.2857142857*B%

except that B = 1.1*1.1*1.05*1.05 = 1.334025 (instead of yours 1.1*1.05*1.05 = 1.21275)

3.

with 2.5% for 600 points, you wrote :

%increase_mast = 100*(mastRat_added)/(28800+mastRat_total)

Adding in the numbers at 7000 mastery rating, 25000 spellpower and adding 100 mastery:

%increase_mast = 100/(28800+7000)*100 = 0.2793296089 increase in absorbs

OK you did not take the same amount of mastery at the beggining.

Let's go with my formula with your datas :

PWS = Base Heal * ( 1 + 1%* SP / ScoreSP)*(1 + %Mastery)

%increase_mast = 100*(2.5%*mastRat_added)/(ScoreM*(1 + %Mastery))

with ScoreM = 600.

so can also writen :

%increase_mast = 100*(mastRat_added)/(24000*(1 + %Mastery))

With +100 mastery added and 7000 mastery on gear (including the buff raid of 3000 mastery),

%mastery = 2.5%* (8 + 7000/600) = 49.1667%

So

%increase_mast = 0.2793296089

Whis is exactly the same result as you.

So to summarize :

for the same amount of point of INT or Mastery

%increase_INT = 0.2826152081*B (with B= 1.334025 ) = 0.377

%increase_mast = 0.2793296089

So we are agree together that for PWS :

- INT is stronger than MASTERY on Equipement (except gems).

- MASTERY is stronger than INT on gems because of the bonus 2:1

We are also agreed that INT calculation does not take into account OverHeal estimation which reduce the power of INT compare to Mastery which will not create OverAbsorb if PWS is applied on tank for Rapture.

edit : i have canceled this remark because it is not applicable to PWS since INT is including in the absorb and there is no healing part which can Overheal.

So your long memo to explain me that i was wrong was not necessary because i have not not writen anything else for the PWS alone that you wrote.

I quote me :

1/

In any condition of gameplay INT is above Mastery** for the same amount of point**.

2/

For **gems only **, we can discuss.... but my conclusion is the same **except** if

- **we take into account the Overheal which reduce the INT stat **compare to Mastery stat (and only if absorb made by SS and PWS do not depop)

or

- **Gamplay is full oriented PWS because margin of INT stat is not suffisant to compensate the double value on mastery gem**

4. Gameplay conclusion

If you consider a standard gameplay with 70% absorbs then there is no way you are going to get intellect being better at 2:1. It requires very heavy overheal on PoH to reach that.

For PoH crit adds 0.001664564943% crit per stat point. At 13% base crit this is 0.001473066321 increase ignoring overheal per stat point. We have shown that mastery increases absorbs by 0.0028% per stat point at 50% mastery.

Absorbs are now 50% of PoH so 1/3rd of the PoH amount meaning mastery increases PoH healing by approximately 9% when all overheal is ignored. This might seem great, but overheal completely obliterates the value of crit for the actual PoH heal. And it no longer adds extra aegis. Crit overheal amount is well over 70% for me (again sampling 30 PoH crits from the logs). Crit is actually a pretty poor stat for PoH, due to the fact that we tend to spam PoH on the raid constantly even for low deficits.

Make the complete gameplay rotation, mastery is poor compare to others stats for PoH (and more poor for the others spells that you use inside the disc gameplay).

The up from 30% to 50% has improved the mastery behavior on PoH but it is still poor compare to INT and Critical stats. and is completely useless for all others spells.

I understand your comment about the effect of critical which is not completly used because of our overheal ratio on PoH.

We need to study both.

First without considering OH and adding in second step the effect of OH on the stats.

As we have different canonic formula but same result at the end, i am sure that you can see it in your simulation when you combine all together all the spell with actual gameplay of disc.

For example (and once again without introducing effect of overheal of stats)

[TABLE]

PW:S 9%

PoH 15%

Atonnement 6%

Aegis 30%

SS PoH 30%

Others 10%

[/TABLE]

Which is a tipical gameplay absorb oriented (84% PWS / POH)

I find the following result :

[TABLE]

For +100 of a given stat

SP INT CRIT MAST HASTE

0,352% 0,435% 0,180% 0,161% 0,224%

[/TABLE]

Which lead me to the conclusion that INT is "always" better than Mastery even on gems.

("always" has to be ponderate with OverHeal done with INT / CRIT on PoH/atonnement and the others spells)

on this example, Mastery is better than Critical because Critical will create more OverHeal than mastery will do.(difference is mainly on the healing part of spells like PoH or "others spells" category)

Haste is a very good stat as usual but is limited to burst mode. If we consider that burst mode is most important behavior of the disc gameplay , then haste is very strong but i hesitate since there is a relationship between Haste and Spirit.

**************

To conclude, i would be enjoyed to continue this discussion, but first agree on point 1, 2 and 3 because we are in line together.

then , we can go more deeply in point 4.

We have shown that mastery increases absorbs by 0.0028% per stat point at 50% mastery.

NO !

We have shown this value for PWS and PoH done under SS, not for PoH spell !

For PoH without SS activation, it is arround 0.0012% per stat point at 50% mastery. (it was at 0.008% before the change on Aegis)
