I apologize if this has already been posted here. I tried searching for Akil'zon, but the forum search isn't working correctly right now, and I didn't see anything about the boss in the "Known Issues" thread. I also scanned the first page to see if anything was already posted. So, onto the meat.
I've seen a lot of threads and posts popping up about this encounter in Zul'Aman. Very consistently people are saying that they had no issues downing the boss on the first couple of days after the release of 4.1. Quite suddenly, most healers are finding themselves unable to heal through the damage. Many of these healers obviously heal in raids and seem to know the ins and outs of their class and role.
The root of the problem appears to be Static Disruption. It could be a combination of that and damage from the birds as well. Mainly though, the fight becomes exponentially more difficult with each melee that is in the group. Even one makes it much harder, plus pets and supposedly even the panther that appears as a result of submitting an Archaeology fragment in the beginning of the instance.
Now I know these instances are supposed to be hard. I have no problem with the difficulty. I wipe somewhat regularly in these places while I'm healing on my Priest and learning how things go, and it's still fun for me. However, this particular fight seems to be a bottleneck that is holding many groups back.
Thank you in advance.
Editing this in as I've seen it pop up as a theory. I have no idea how the instance servers work, but as some people are saying it's fine, no problems, and others obviously just can't get it done, perhaps some of these instance servers are bugged while others are not. I don't really know how to describe it better than that as, like I said, I have no idea how that works.
