Ideally, there would be a solution out there that captures/replays your casting history for a given fight so you can pick out where the dead spots are in your casting rotation and fix accordingly. In lieu of being able to fraps your fights so you can watch the replays, you can use these log parsing tools to compare total casts for a given fight with your peers to make sure that you have roughly the same casting up-times.

If you go down this path, I recommend continuing that discussion in the warlock wws help/analysis thread.

I noticed last night that with my current rotation I am having a few issues. I think it is due to the amount of haste I am atm but Im curious as to what the rest of you think. Right now I go with the LT/Immo/CB/Conflag/Inc til CB/Imm are up/in need of refreshing. Of course it goes quite smooth in the first part of my rotation using my 3 backlashes for my incinerate casts. My questions are this: Within that first immolate Im getting off of course to CB's and 2 conflags but due to my lack of haste (I think raid buffed its roughly 460ish) Im sacrificing 2 of my backlashes (1 to a CB which seems virtually a waste unless it crits) and one to an immolate due to me casting a conflag then a chaos bolt, and 1 incinerate that is clipping the end of my immolate dot leaving 1 backlash point up. Now do I waste it on an immolate for the additional dmg for the next set of incinerates Im going to cast since I just used CB/Conflag and there both down or do I roll the dice on one more incinerate. Im unsure if this would be a dps loss since atm I am just using it to cast a quick immolate. My second question is would having more haste (around 600+ raid buffed) smooth out this rotation and allow for all 3 incinerates to get off before the dot is clipped thus solving this problem.

I assume you mean backdraft, and will answer your question under that assumption. Your priorities stay the same even if you're under the effect of backdraft. If you have one backdraft charge left and your immolate dot has half a second left and you have to choose between incinerate and immolate, you should choose to begin casting immolate. I repeat: nothing should change in your priority list while backdraft is up.

This is a commonly-known problem. The issue is that conflagrate only lights up *after* the double-latency period of (client tells server to land immolate) (server tells client immolate aura is up). The good news is the *other* conflag bug, that it will light up but be uncastable if another warlock in the raid puts up immolate, will counteract this.

Generally speaking, I put a chaos bolt or CoD in my early rotations after immolate and before conflag. Most of the time there's enough separation between immo and conflag that the problem doesn't reoccur, but when it does, I just move to incinerate or whatever. Chalk it up as a DPS tax for being such an all-around awesome class.

I'm currently using Conflag, Incinerate, and Immolate glyphs. My spec is 3/13/55. I'm wondering how much spirit I should have before switching to Lifetap glyph and would I replace the Immolate glyph to do so?

Use the LT glyph unless you have Improved Soul Leech. If you've got ISL (which isn't in the 3/13/55 spec), you can change LT to Immo for a fairly small DPS upgrade. If you've got 3/13/55, you would see a DPS improvement right now with the LT glyph. This is a pretty universal statement, regardless of your actual spirit level (although I guess if you have zero spirit, it might be iffy).

The reason is that even with relatively low spirit, the bonus from the LT glyph is significant. It might not be worth a GCD spent not DPSing, though. So if you don't have the mana regeneration from ISL, you're going to be life tapping anyway, might as well get the buff. Most models I run with simcraft (as well as my own experience on dummies) indicates that "lazy lifetapping" is probably better than being aggressive about chasing the buff (e.g., Life Tap when you're below 50% mana and have the time to do it, don't LT just to keep the buff up), unless you also have 4t7.

I'd recommend he just run SimulationCraft against his current gear with and without the Life Tap glyph, regardless of which destruction spec he uses.

For my gear, a mix of Ulduar and ToC25 gear, mostly, Life Tap is predicted to be significantly more DPS than any other option even with an ISL build (that I'm using now).

I got a question about effective haste vs actual haste.

Under full raid buff i notice with roughly 590 haste rating i manage to fit incinerate just nicely into the rotation such that my last incin will end right before the cd of conflag and duration of immo.

If i get more haste I will only be building more empty time between my last incin and the next conflag/immo. I could fit a corruption in or a unnecessary LT but that dosent seems to be optimizing my dps. I may need about 900+ haste rating in order to get another incin in.

So my question is, if i found this "sweet spot" haste rating, does it means that the effective haste rating scaling between this "sweet spot" to the next one (whereby i can fit another incin) is actually lower than the one in simucraft?

p.s. I hope you guys understand me, English is not my first language.

or you're simply gaining time to toss some more spells.. think in this way

It is true that haste has a nonlinear value, which makes the value of 1 more haste rating vary by how much you already have (and it's in part a "step function" based on how many more incinerates you can fit in, but not entirely). Simcraft handles this, if you run the simulation on *your* gear and spec (and tweak it to cover your raid setup). That'll tell you what your personal scaling values are, you don't need to use the default ones if you're worried about that. The default ones are all made with certain assumptions about gear and raid makeup.

Just tested it on the ptr, my normal conflagrates hit for 4028 damage and the crits were around 8500 and the ticks were not affected by conflagrate damage since they always did around 390 damage (3 ticks).
