I'm getting to the gear level now where I can look at making AiS my focus dump all the time (especially since I have a trinket with a haste proc, as well as the 4T13). My AiS is still about .1s slower than I'd like it to be, so I was planning on reforging some of my gear to haste to get my AiS to where I want it, but the OP recommends reforging into crit.
So what I'm wondering is, is it okay for me to reforge some of my gear into haste to get my AiS fast enough to be my main focus dump, or should I keep everything reforged to crit and just accept the slightly slower AiS cast time.
Also, now that I'm switching to AiS as my focus dump, what should I use in place of my old AS glyph? I'm currently running SS and RF, so I could either take AiS or KS, but I'm not sure which is better.
Lastly, which would be better for PvE as my weapon, between and ? The PvP one has more weapon dps, but I'm not sure how good the proc is on the Raid Finder one (I won't have access to a proper version of the PvE one, only the raid finder one).
Theoretically, at high gear levels, using an AI only focus dump (with only using enough ASs to proc the T134P when off ICD) rotation is higher DPS than a mixed AI/AS focus dump rotation. However, in practice, most boss fights, especially on heroic, have high movement requirements or interruption mechanics that make it difficult to consistently perform AI casts, which can result in the mixed AI/AS usage actually being better DPS in practice. Thus, I recommend that approach. However, highly skilled players can possibly perform the AI only focus dump case well enough to make it still be better.
For comparison purposes of the 2 cases, I will use FD and my current 397-8 ilevel gear. I currently use a balanced AI/AS approach with getting as much crit as possible, haste above the 1235 rating amount, and maintaining a good amount of mastery to increase AS and AoE DPS. FD lists this as 43584 DPS.
Going the AI only DPS route, the best stats are as much haste as possible while still maintaining decent crit levels. Mastery is sacrificed since it is worth less since you are taking less total shots with the AI cast times and autoshot lockouts. Hence, your AoE DPS will suffer a little with this approach die to the loss of mastery.
You mention using a haste trinket. I assume this is the Starcatcher Compass. The Compass provides some soft haste caps. Your AI casts are at the 1s GCD during glyphed RFs at 3292 haste rating for normal Compass and at 2918 haste rating for the heroic Compass. I definitely would not suggest stacking haste higher than that.
In FD, without doing any reforging or reglyphing but going to the AI "only" focus dump case, I get 42994 DPS for a loss of about 600 DPS, but this amount is incorrect since this FD case fired the ASs to proc the T134P immediately instead of waiting until after the CA phase. This wasted most of the haste from the proc since with the glyphed RF and the trinket proc too, AI cast time was at 0.856s. I will talk to Zeherah about this to see if it is a bug or just an incorrect setting by me. Anyway, if the ASs are cast after the CA phase, the DPS should be much higher.
Now concerning reforging, despite the increased secondary stats on most of our gear pieces with DS gear, we actually lose some reforging flexibility and do not really gain as much secondary stats as one would expect due to the BiS melee and ranged weapons not having any secondary stats. That along woth the agility trinkets not having secondary stats to reforge reduces both what the possible stat pool could be and the number of slots that could be reforged. Thus, with my gear, I could only reforge to 1890 haste rating out of the about 4500 secondary stat pool after being hit capped. This resulted in 43140 DPS, which is about 150 DPS improvement before reforging but still about 440 DPS below the mixed focus dump case, mostly due to when the first T13 4P proc is occurring. With that fixed, this case is probably a little better. With different normal gear pieces than what I have or with heroic versions, higher haste amounts can be achieved, which will increase the relative DPS.
To get a true feeling for this case, another setting to adjust is the Save Focus for CS setting. Since with the T132P focus generation, casting AIs can result in a lot of wasted focus, especially if saving enough focus to cast CS after the AI. Hence, it is best to turn this setting off in game should should try to avoid capping focus if you can with always casting SSs to gain enough focus to cast either AI or CS and avoid focus capping. Changing this setting increased DPS by 427 in this case while it only increased DPS by 157 in the original case since with using ASs, it is much easier to avoid capping focus with that setting.
The next question is which glyph to use instead of the AS glyph. The options are:
AI glyph: +255 DPS in this case (was +171 before fixing the Save Focus For setting). A quick estimation is that this glyph saved about 200 focus over the 5 min sim.
KS glyph: -40 DPS in this case. This is because between the higher damage from AI then KS, the shorter cast time with the higher haste levels making AI casts closer to the GCD, and focus not being a concern with the T132P and 1 point in Term, the extra KSs are only a small DPS gain in the KS phase and does not make up for the loss of DPS over the rest of teh fight when KS is not being performed.
Hence, the AI glyph is the best option in this case.
So to summarize, the original mixed focus dump case after fixing the Save Focus for setting is 43742 DPS, while this case is 43882 DPS. This is only 140 DPS better in FD, but the actual DPS increase is larger once the first T134P proc is corrected until after the CA phase. Even then the DPS increase will only be a few hundred DPS at most. This difference is reduced anytime you have your AI cast interrupted or fire AS instead when moving such that on most practical fights that the mixed focus dump case probably works out better. Furthermore, your AoE will be higher with the extra mastery from the mixed focus dump situation.
I couldn't see the ranged weapon options to provide a response concerning it, but usually the higher weapon DPS version wins out. However, I suggest checking FD to get another view on the situation.
