When Haunt, refreshes Corruption, it "rolls" it. So on Thaddius, if you refresh a Corruption that was cast when you didn't have any charges buffing you, you'll refresh that cast. If you had casted the Corruption while you had 10+ charges buffing you, then it would stay at the higher strength the entire fight. So I don't think this would be classified as a bug.

What is annoying is recasting Corruption. There's a few cases where you might want to do this (Thaddius charges, Malygos patches), but the game won't let you. Often when I try to manually recast Corruption I get a "A more powerful spell is already active." error, even though that isn't really the case. It doesn't seem to be calculating your buffs when it tries to guess which is more powerful. Therefore, it sometimes is beneficial to let Haunt and Corruption fall off for a brief time in order to recast a much stronger Corruption and roll it through the rest of the fight with Haunt.

Then you might ask yourself if that is "working as intended". Naturally you will always want to avoid clipping, but in some cases it might be efficient. The morale must be: never clip Immolate.

Anyways, have someone tested if some of the bugs are fixed on the PTR? Nothing is listed in the patch notes afaik :S

Has anyone else had problems with the imp going mad and pulling bosses ( although he's on passive/defensive)?

Nope, but if he did I'd smack him around and tell him not to do it again or the next Immolate will be hitting him and his ass.

I had the same problem on Krik'thir in Azjol-Nerub. After a given amount of time the next watcher-group seems to automatically focus a random(?) target. If you are the target and your pet is on defensive, it will attack the group. This will definitively not happen, if you switch your pet to passive.

Is it confirmed that Corruption is rolled now? I know we had a bug initially where a Haunt refreshed Corruption was recast with the old modifier of 96%. It seemed obvious that they would only fix the modifier and not the recasting of Corr on refresh.

I can't say much about the "A more powerful spell is already active" effect, though I can imagine that a previous one was cast with a trinket proc which you don't have on the recast. That would mean that percentage modifiers like Thadius' charges aren't calculated for the power comparison. That would be a bug then.

One thing that may help when reporting bugs is to list which glyphs you use. Since these are a new dynamic to the game, they could possibly be the culprit.

I don't think that's a bug. My guess would be that on defensive, the imp only starts to attack once you get in a mob's threat table. With normal mobs, this usually means once you cast something on it. But bosses, I believe, automatically put everyone in the raid in their threat table, so if the pet is on defensive, it's going to attack. Easy solution, of course, is to keep it on passive.

Or I may be completely wrong.

Well, I did a few tests and this is how it works:

- Debuffs on the mob (specifically SE, Haunt, CoE) are calculated EVERY tick, so you get instant benefit when these are put on after your dots.
- +spellpower effects are calculated every time Corruption is refreshed, either directly or by Haunt, i.e. they do not "roll".
- You can not manually refresh a Corruption that was cast with a higher spell power value, which is the only thing that produces the "a more powerful spell is already active" message.
- +%damage effects (this includes Ferocious Inspiration as well as the Thaddius/Malygos buffs) are only calculated, when manually casting/refreshing the dot, NOT when Corr is refreshed by Haunt. That means you have to refresh your Corr on Thaddius as soon as you get your charges. If you can't, that's probably because you got a +spellpower trinket proc at the beginning.

I've had this happen on heigan, my imp pulled heigan and we wiped, after the rez i resummoned him and he was on defensive.

He's only ever done this once so far though.

Not sure if that's what you mean.

While I'm not sure if I would classify this as a bug, but a number of times I have briefly pulled aggro from the tank after he has pulled a pack of mobs with a ranged attack. Seeing as i am only standing there doing absolutely nothing when this happens, i can only assume that the healing effect of Fel Armor is generating healing threat.

While admittedly this has not caused a wipe since tanks are on the ball and it doesn't take much threat to pull them back, isn't this just an unnecessary complication caused by a passive spell on a player?
