After wiping all night Wednesday, we killed him on the 2nd pull last night and were rewarded with zero tank loots, just a bunch of caster garbage Note: we're a social/casual guild that raids so our issues will be different than some but probably most people needing advise are in our boat.
The biggest issues for us was the obvious, not getting people off spikes quickly enough and consistantly and positioning. His big, nasty cleave just doesn't seem to discriminate and hits the MT and two other people in front of him. I've seen times when all three tanks were having a group hug and the priest standing 10 yards behind us keels over dead on a Saber Lash. Getting people to GTFO the way and not stand there when he stops Bone Storming and we have to drag him back to the center of the room.
No, he cannot be taunted. You just have to be ready to unload on him as soon as he breaks out into phase 1 again. The DBM timer seems to be off by a good 3-5 seconds and he's 'live' before the timer winds down. I try to make my first two globals a SS and a Conc and slowly back him into the center. The tanks have got to learn to 'dance', making their moves at the same time.
All I can think of at the moment.
your hat may be nice, but I have the little white tank top that says Legendary right across my boobs. I win. (or more correctly, H wins)
