I think what you're observing here is actually the opposite - it scales with the spell power from glyph of life tap even if the life tap buff is NOT up when you cast dark pact. This is (presumably) because the game procs the glyph first, before checking your spell power to determine the mana return.

nvm, noticed someone already mentioned the Demonic Aegis bug

I am affliction /destro specced.

If I cast FA while affliction i get (let's say) x spell power.
If I switch to destro, equip the best passive SP trinkets i have, cast FA and then switch back to affliction, the FA bonus remains the same as in destro, thus gaining about 100 spell power.

Is this working as intended ?

Since this morning you lose Fel Armor with activating another specc -> Demonic Aegis bug is fixxed.
EU Server.

Downranking Lifetap seems to have been nerfed. I now gain 41 mana from rank 1.
The top 2 ranks seem to be working as normal but there is a huge drop from rank 7 to 6(2933 vs 1575).

Tested today with and without add-ons and no matter which class I use I get 73 bonus damage added that's it. Not functioning as intended as far as I can tell. Tried every rank.

I've recently acquired Muradin's spyglass after months of it not dropping. I use rank one hellfire to "charge" it before a boss encounter. I've noticed that between 5 and 12 seconds before boss activates (LK with his long pagentry), that the hellfire stops stacking the buff. Sometimes I have enough time to do some damage to the boss and keep my 10 stacks and othertimes I lose the buff and start from scratch.

It is really pissing me off. I'm a demo lock and my fellow affliction lock says he does not have this problem. Anyone else seeing this in game? Anyone figured out how to avoid it? I have the best results if I start hellfire at like 20 seconds till combat and "refresh" the channeling going into the engage.

I'd assume you're getting a shield from a disc priest due to taking damage. Ask the priest not to shield you and you should be fine!

I've had this problem since ToGC.

When I use a dot in a rotation and the time has come to refresh it sometimes (mutiple time per raid)what happens is that the dot does not show up.
I've tried this with different UI:s and with blizzards regular UI and it happens anyways.

To be more clear what I do is: I need to refresh or rather reapply a dot ability, what then happens is that it does not show on the target as a debuff or dot nor in my dotimer. So what I normaly end up doing is recast it over and over, but that does not help at all. -
What I have to do is wait half of the duration of the tic, THEN it shows up in both my dotimer (Buttontimers) and on the target.
The worst thing with this bug, or whatever it is, is that it can occur mid-combat and then not show up for some bosses and then happen again which results in many reapplys before I realise that the bug has occured.

Another lock in my guild have had this happening to him aswell but not on a regular basis.
Anyone else had this bug or know a way to get rid of it?

I had this issue while playing as Demonology - when I went to recast Corruption, the client would erroneously intercept the Affliction warlock's corruption as my new one; this had the unfortunate side-effect of removing my true Corruption from the front of the boss debuff pane, and my addons were unable to track that it was indeed applied.
The only solution I could find was to disable display of all target debuffs applied by other players.

I currently have only my targets debuffs on, so that is not the cause. And I have to add that I have this issue in every spec and any addon and without addons.

Although I guess it can have something with other warlocks having the same dots up. That would probably not leave any room for me finding a solution though =/

I am not sure if we are on the same page or not but the reason why DoTs do not show up properly is because you are not tracking all of your targets which you DoT. Usually happens when you tab DoT adds really fast. If you simply mouse over the target which you think is bugged it will fix the timers or you can just put that target on focus and you will never have this problem. This has been my understanding anyways.

No that's not the same page =) I mean in raid encounters, on bosses. Neither my target bar of the boss nor my Buttontimers registers the dot.

I had a similar (maybe the same?) problem just the other night. I have only just started leveling warlock so am still reading up on it's mechanics but here is what happened to me:

Solo play: no problem.

First random dungeon I go into: no problem

Second random: My Dots dont work properly, not just in the case of refreshing them either. Just randomly didn't seem to apply themselves to my target. Sometimes they would work but when they did not, I saw my warlock cast and the cooldown animation over the spell icon but when I looked under the mobs healthbar, it was not there. Sometimes I had to cast several times before it would work. It was like that with any DoT including immolate. It has only done it on that one occasion and i noticed that i was having the problem mainly when faerie fire was applied to the target so maybe it is something to do with other Dots or debuffs from other players?

Never mind, sorry.

Spell Hit

You wont see it much in solo play, in dungeons you'll it randomly. If you arent at spell hit cap then your spells will miss. That is the exact behavior you are describing.

This bug was fixed

#When casting soulfire and empowered imp proccs, the procc falls off after the cast is finished. (nightfall situation without the instant).
#removed

It has a 15 sec ICD. Working as intended.

Anyone else finding the Ebon Imp summoned from BoD ticks is on aggressive? Ran a couple of icc heroic 5-mans yesterday and there's a couple of times he sprinted off to a nearby mob and even took out critters with the FG in hot pursuit.

We really have to assume that the 2x (down from 4x) multiplier on drain soul is a bug, considering it effectively breaks the drain soul execute mechanic, which is pretty integral to the whole spec. I made a thread on the bug report forums:

World of Warcraft - English (NA) Forums -> [BUG] Drain Soul execute damage halved

There is a bug with Bane of Havoc that can be used (exploited?) to increase DPS on fights with adds.

A phantom Bane of Havoc debuff remains on the target when BoH is replaced with a Bane of Doom (or Agony).

This means that you can cast Bane of Havoc at the start of a fight like DBS and immediately replace it with Bane of Doom. Then when DPSing the Blood Beasts, DBS will take damage from the BoD ticks and 15% "splash" damage from the phantom BoH. You will also have extra GCDs that would have been used to cast BoH before the beasts spawn.

The phantom BoH expires after 5 minutes or when BoH is cast on a new target.

This is obviously not the intended behavior of BoH. Here's the thread to report the bug.
