I set my pet on aggressive on phase 1 and it just works ok for me. On phase 2 I do not bother to use pet

I've always used my pet on Malygos. Never had any other problems than the pet getting stuck after vortex, and that is fixed now. I don't remember reading about other problems than that either and have done the encounter some 20 or so times myself now.

The problem was that after a vortex the pet would eat a breath, not die from it, but still take the debuff. Then they wandered back into the raid and blew up, one shotting everyone. Or so the theory goes. My guild had one night of frustration from this before we did it petless without a problem - but this was weeks ago. I haven't noticed it happening again, and pet behavior on vortexes seems a lot better.

The only bug that I've seen on Malygos is one I doubt very much is related to pets.

Sometimes Malygos comes in during p2 and decides to snack on the raid - I don't see how that one could be related to pets however.

The biggest problem I see on malygos with pets is when I forget to send in my pet after a vortex if he's on passive, or keeping him back so he doesn't get 1-shot by the lords in p2 if he's on defensive - that and from other huinters just letting their pet die and ignoring it (pet = 1-shot dot of variable length and damage for them it seems)

Sometimes, I noticed that the pets (and this includes ghouls and all manner of failguards as well) are going to attack from what they consider behind, but they still eat the breaths. What's even worse is that sometimes if the pet gets caught in a breath, Malygos turns around about 70-100 degrees and may breathe on the melee on that side.

Confirmed to work while ExS & SpS are ticking. Confirmed to work in P1 both on the ground and while in the vortex. I continue use a macro'd FD:

Previously FD had been bugged for me like everyone else. I basically had to sit down unless my MD was up.

Can't reproduce the Aspect change bug.

Pets aren't able to attack anything on the Kologarn encounter, it seems. They just stand around, unable to get to any of the three targets (Right Arm, Kologarn, Left Arm).

EDIT: Moving very very close to Kologarn then commanding pet to attack seems to work.

Can't reproduce but it happened to me. So it is something that definately does happen now and again. I believe it is tied into dualspeccing. Goes away if you log out.

No, it's not tied to dual speccing as my hunter doesn't have dual spec yet. I had the same thing, until I died. It basically something that was introduced by the patch since it happened on the ptr also. It seems blizz figured it was an artifact of the character copy, but imo it looks like since it affected live, something in the patch did it. Since it goes away with death/relog though it doesn't really matter.

One lovely bug though is the Wild Hunt effect that is either taking longer than it should to apply to pets or only does after you relog or dismiss/summon pet.

FD doesn't work on Razorscale. :/
(Killed the dragon with 3 hunter, all of us died because of FD-bug, so it's quite sure. )

I killed Razorscale last night on 10 man and 25 man without any issues with FD. Is your FD just getting resisted? What part of the fight are you dying on? Adds or Final Phase?

Hm that would explain the rather surprising amount of interest she gave me...

I did Razorscale on 10man while paying very close attention to my threat and saw neither an error message nor a reduction of threat when I FDed. I don't have any status message hiding macros anymore; it simply seemed to not be registering. Since Omen now pulls directly from the game's internal threat calculator instead of calculating it independently, I'm inclined to believe it is not an issue with Omen.

Confirmed. Razorscale doesn't resist FD. You just can't FD away the aggro you get from him.
It's exactly how it was with Malygos. You could FD to drop your aggro on the adds, but not on the boss himself.

I've noticed that you can FD to drop your aggro on Deconstructor. However you can still get both debuffs cast on you even when FD'd. Only once out of 10+ attempts did I FD during a wipe and actually lived.

Defensive or even aggresive works here perfectly.

Defensive works very well for the entire malygos fight. However I wouldn't say "perfectly."

My pet did die once while i had him on defensive at the beginning of phase 2. However it was unlucky as he went to go attack the Nexus Lord that was furthest away from the first bubble that dropped so my tanks couldn't tag it before it wacked my pet to death (all of 2 swings).

Still, I would highly suggest keeping your pet on defensive for the Malygos fight. It requires 0 pet management and there is a very low chance that your pet will actually die.

So when I did my talent tree Tuesday I noticed I am still having the same problem with black arrow not showing up on my talent tree. On top of that it shows me at 15/52 spec. The wierd part is once I hit 68 talent points I could not put any more in. So I missing 4 points. I was fine monday but now cant do it. Would you suggest just relearning these again, or could it be a ui issue that would just need to be reset?

It's always been the case that if you feigned and moved too quickly, the ability would go on cooldown but you wouldn't drop threat. This seems to have become exacerbated somehow with the release of the expansion (see first page posts; people have been noting this problem for awhile) where sometimes, if you don't hold Feign Death for at least a few seconds after the time it takes your character to hit the ground, the aggro wipe won't truly go through; you just become untargetable while you're Feigning Death, while keeping your place on the threat table.

However, it seems to depend on the mob's response time, which varies (if you've ever seen your pet play tag with a mob, you know what that means), making how long you need to hold Feign Death hard to gauge. I've resigned myself to holding it for a few seconds after hitting the ground when it's absolutely crucial that I not pull threat; then, even if my threat is restored, odds are the tank's had enough time to pull ahead of me again on the threat table anyway.

Yeah, I've grown used to pausing for a couple of seconds after my FD to ensure that it goes through. On Emalon, however (and reconfirmed last night), no amount of waiting (while feigned) seems to work. I just cannot drop threat on that fight.

Can anyone else confirm that this is happening for them? (FD not clearing threat on Emalon).

Hmm, that sounds like a different bug from what people saw on Maly and now on Razorscale where FD just appears to do nothing at all. I most definitely feigned when Razorscale was on me, didn't get a resist message, and she didn't even drop me as a target; and others report that when they feign on her they don't even see their aggro disappearing in the first place, unlike what you've seen. What you're describing lines up more with the general "moved too soon" bug with how aggro appears to disappear, then returns. (Which personally I'm wondering if is intentional, because Blizzard wanted FD to actually, you know, look like feigning death.)

My pet seemed to experience some pathing issues around rocks when standing on the left side (as the raid faces). However, in later attempts I stood toward the right side of the room and my pet functioned normally, being able to attack the right arm and Kologarn.

I'm not sure where any of you were standing, but this simple fix worked for me.

I am starting to think it has to do with air phases. I was able to dump a portion of the threat right before it went up. When it got back down, even before I fired a shot, I was already on the top 5 in threat...Has this happened to anyone?
