Aside from this AOE the only real thing to watch for is an add that will come every 30 seconds or so. This add must be killed quickly as it will eventually blow itself up if not killed in time.
Burn the named and the add and grats on loot.
We tried a few times this one by killing the adds but could not do it that way (well, we did bring him down to 7%....) mainly because of the knock forward you get from them (when they blow up ?)
So we finally decided to have our ranger to pull adds away and we killed it pretty easily on first pull.
The tank pulled him to the left wall and we had all our raid force at max heal/dps range into his room. When an add spawn, the ranger pulled it into the room we came from and kited it untill it explodes...
Add should be pulled away from the raid force, have a brig do this to make the fight easy.
It will eventually throw itself at the mob and explode and then another will pop. This allows your healers to never be interrupted and your dps to stay on the name and burn him quicker. Adds repop the moment they explode.
