I see in your spell priority list that casting a MC Incinerate is listed as a higher priority than a Decimate Soulfire. However in the sim chart Soulfire has 3k higher DPE. Could you explain which spell has priority in the execution phase?

I had thought as you until I started looking at heroic boss fights.

I don't have WoLs to back this up, however what I have observed from watching individual fights with my present stats (13% base haste + SF buff + DI), MC Incinerate is casting at 1.1 to 1.2 seconds and doing 7.2k non-crit damage and Decimate Soulfire is casting for 1.4 seconds and doing around 7.5k non-crit damage. As such, the MC Incinerates are working out to slightly higher DPS under execute phase.

Also, until Blizzard fixes the meta requirements for Chaotic, I would use Lightning Dream Emeralds (Hit/Haste) in yellow sockets (if below hit cap and not close to haste threshold) to fulfill the meta requirement.

Anyone else seem to have problems with the Doomguard? I'll summon him and often times he just sits there. Doesn't matter if there's a doom up already or not or even if I reapply it once he comes out, even tried forcing pet attack. Infernal hasn't failed for me yet so I just use it instead.

Am I missing something or is he just poorly coded?

Here is a Macro I found useful from a friend of mine. This will add Felstorm to your Spells. If this Macro was posted in the old Warlock thread then im sorry.
#showtooltip Shadow Bolt
/script UIErrorsFrame:Hide()
/script UIErrorsFrame:Clear()
/console Sound_EnableSFX 0
/cast Felstorm
/console Sound_EnableSFX 1
/cast Shadow Bolt

I was wondering if anyone has done or could do the math regarding whether or not Demo has a soft haste cap which may cause it's weight to drop in regards to haste > crit > mastery.

My experience so far in avg ilvl 343 gear is that with decimate and molten core I am approaching 1 sec cast times. Shadowolt obviously is nt close, but is still at 1.8 sec by keeping up Imp. Soul Fire. This makes me wonder whether the value of haste may diminish as we become well geared and our nukes encroach on the GCD.

Now, I realize that MC, Decimation, and ISF do not increase HASTE, but rather decrease cast time. This means that Immolate and corruption damage is unaffected and raw haste on gear will continue to provide dps increases in this regard. But will those two spells continue to be worth gearing for haste past a theoretical sweet spot? Or will we eventually want to hover at some haste % in the future and otherwise reforge those additional points into crit or mastery?

As an aside, yet slightly related discussion - most of the currently available dps cloth epics have mastery on them, a stat we currently are ignoring. Is there a consensus on how this may affect Demo's viability as raids progress deeper into content as opposed to Afflic or Destruct who value mastery much higher.

I appreciate any intelligent discussion regarding these points or any math that may back up any one point or another. Thanks.

Sorry if this should go in the simple questions/answers forum. Thought it would be slightly more appropriate here and I haven't seen any discussion on it. Does HoG's place on the priority list still apply if I've just just refreshed immolate with fel flame (for whatever reason)? Does the nuke itself and the unnecessary re-refreshing of immolate really come before refreshing BoD/Corruption if they, say, drop off?

Fel Flame only extends the duration of Immolate a relatively small amount, so the refresh from a Cremation-empowered Hand of Gul'dan is not "unnecessary" as you'd still need to refresh it quite soon anyway.

It's not really possible to determine from the posted simcraft output whether deferring HoGd in the situation you describe is worth while because the situation you describe does not occur in the simulation under test and the DPET of HoGd does not factor in its side effects. If you could construct a scenario where it did occur then you could trial different priority lists to see whether it appeared to be beneficial or not. However, in a different scenario where movement or immunities occur many other things would also need to be re-assessed in the priority list. Otherwise all you can hope for is peoples' gut feelings on the matter.

(Snipped you post to save room) Improved Soul Fire does provide pure haste, and to answer your question, yes there is a "soft haste cap", after 50% haste (2639 haste rating) the value of haste begins to drop below that of crit, this is mainly due to the GCD being 1 second.

The value of mastery as you gain gear will actually increase ver so slightly, due to gear having a slight effect on the proc rate of Impending Doom, as well as your pet damage increasing, as pets scale directly with our stats.

The main reason you prioritize HoG over corruption or BoD is because you are using it to refresh immolate. If Immolate does not require refreshing then the DPET of both BoD and corruption are higher. So if the CD of HoG ends at the same time BoD or corruption require refreshing AND immolate has a long enough duration left on it that it does not require HoG to be used straight away, then yes, cast corruption or BoD first, however, after this HoG will be next on the priority list.

Please Note: I am updating the thread to reflect recent findings in the Simulationcraft for Warlocks thread, and specifically this post.

Currently the pet to use in a raid is the Succubus, while glyphing Lash of Pain. If/When this changes, this thread will once again be updated.

Note: if we're using the Succubus for single-target fights the talent "Dark Arts" doesn't provide any benefit, so we can pick up even more of the wonderous filler tat that masquerades as "utility" at the bottom of the demo tree instead.

No because the demo tree has the minimum 31 talents points in it so you can't remove the DA talents. Furthermore I ran simcraft with three points in S&F, two points taken from Emberstorm or Improved Immolate, and both ran roughly 100 DPS less than the current build in this thread. Someone in another forum I read made a suggestion that since Demon Soul with a Succubus provides 10% more Shadow Bolt damage that three points in S&F would be a DPS increase. According to simcraft, that's a negative, no matter where you get the other talent points.

Edit: misread the post, thought he meant taking points out of demo and putting it in destro.

Lash of Pain is making up 25-29% of my total damage in my encounters, with increasing efefct during movement fights. The closest to LoP is Shadowbolt at 18%.

Has anyone evaluated the value of mastery with the Succubus?

My succubus is getting 5.2k LoP's every global versus my felguard's 2k autoattacks every 2 secs and an average 5k Legion Strike. She wildly outperforms the felguard outside of burst rotations.
