I can confirm the SE bug is indeed back. They broke it again it seems.

I am confident that blizzard will hopefully resolve this issue in the next upcoming patch. This is a fairly severe issue I believe and I feel for you guys that fill your raids with two or more affliction warlocks. If anyone has any prior information on this shadow embrace issue please don't hesita
te to inform us. I have placed these concerns on the wow suggestion forums too.

Demonic power does not appear to be affecting imp. I tested the imp with and without the demonic power talent against a target dummy several times. Imp DPS was unchanged and number of casts was unchanged. I did the tests a few weeks ago and reported the bug on the official forums. Demonic power affected the succubus normally.

I'm just shooting from the hip on this one...I have no idea about how hard it would be on Blizzard's end...but can't they just make it into a temporary self buff, rather than a debuff?

I mean...just change it to be similar to a Molten Core type of buff, which refreshes everytime you hit with the particular spell...then you can put 10 affliction locks in the same raid...and we can all dps in peace.

It's been said before: They don't do that because of the HoT reduction SE also applies. Also, Blizzard seems to dislike "band-aid fixes". See also: Glyph of Souls.

That also has a large gameplay effect just for the damage buff, in that it does not tie the DoT damage to the current target. The debuff implimentation has the effect, probably intentional, of making our single-target DPS significantly higher than our multi-target DPS, which may have been one of the things our single-target DPS was balanced against pre-WLK. A self-buff is a very radical redesign, not a minor bug fix, and should not be considered unless the bug is otherwise un-possible to fix. Since it sounds like it was working right at some point, we shouldn't worry about it.

As a related note... when it's working again on the PTR, whenever that may be, a pair of warlocks should double-check the healing reduction doesn't stack. That would probably be bad.

Still no fix for the Drain Soul spell being auto-canceled when any mob or raid member dies? That bug is getting real old, real quick.

-from patch notes on WoW forums

No idea if it's actually fixed or not, but this is what is intended to go out when patch hits live.

"Will now gain the correct damage modifiers for the creature type of the target" shows up for a few skills in the patch notes (corruption, haunt, unstable affliction, soul siphon). Does anyone know what the heck this actually means? What was the bug?

When that happens, others don't even see you shooting and you definitely don't do any damage.

The bug was actually on everlasting affliction and caused corruption when it was reapplied by haunt to tick for lower values according to the old coefficients (the ones before the buff-hotfix on cor-immo coefficients).

I'm with Zakalwe on this one, probably the few +spellpower vs undead trinkets lying around. The thing with everlasting affliction not using the right modifiers was mentioned as a separate bug (that is also fixed). Remember, the PTR is usually not up-to-date with the latest internal fixes. It may still be broke in-game but we'll get the fix by patch day. Of course, the fix is not 100% guaranteed to work, although I wouldn't sweat it too much.

I'm still experiencing the immolate bug. I know one of the other affliction locks in our guild has problems with it as well. I can't figure out what exactly causes it, but it might be that the new one hits just as the last tick was about to tick. Has anyone tested this on the PTR?

Have you tested on both live and PTR?

Was this on live or PTR? On live, demonic power is working just fine. I just tested myself, and his cast time is reduced from 2.5 to 2.0 as it should be with 2/2 demonic power.

I tested the demonic power bug on live only. I found the bug three or four weeks ago; I just tested now and got the same results. I am using recount to check the number of casts in a given period when attacking training dummies. I had just respecced to a version of 0/30/40 and was testing dps both times I encountered the bug. Tonight I resummoned several times and even suicided to ensure I had a "fresh" demon. This could just be a bug with respeccing if people are not encountering it. I will test again tomorrow.
I took the improved imp as well as the demonic power talent and am finding that the imp does a fairly regular amount of damage, currently 260-265 dps on the heroic training dummy. If the talent is working properly for other people at my gear level (t7-7.5 epics) I'm guessing the imp should be doing 310-320 dps.

Just tested this on the PTR and Demonic Pact still does not take the spirit->spell power conversion from fel armor into account for calculating the 10% buff.

To reliably reproduce the immolate bug:

1. Equip an "on use" trinket with a spell power increase.
2. Use the trinket and cast Immolate
3. Click off the trinket buff and recast Immolate

You'll notice that the cast is allowed to complete and the direct damage will be done but the dot will not reapply. There is no error message such as "a more powerful spell is already active," but this is most likely the reason. The best work around that I know of at the moment is to be very certain that you allow enough time for any spell power buffed dots to fall off and don't clip anything by even the slightest immeasurable amount or you'll end up wasting cast time and mana.

I don't know if that could even be considered a bug, except that it should give the error message you mention. And if you're regularly clipping your last immolate tick, you're doing something wrong anyway - consider this "bug" a good opportunity to teach yourself to play better.

Dark Pact has the same problem (allthough it doesn't really matter).

It happens even when you don't clip.

No, it's only if you clip the dot. What happens a lot of time is I'm used to immolate having a certain cast time and some haste effect I've not noticed is active and I'll clip the dot. My workaround is just to throw something inbetween UA/immo if I've got active haste effects up that weren't there before, or let them fall off before recasting just to be sure. Better to miss a couple of ticks on those two rather than clip the immolate and waste a whole GCD.
