Also, is HM BT overtuned? We come down after the cutscene and instantly get brought to about 5% where he then seems to wan't to stomp and kill most of us.
Overtuned? I don't know. But it's certainly an obviously unfinished and half-assed encounter. BOSS BEAST 1!
Send one of your tougher guys in first, they pop their CC breaker and a defensive cooldown, turn the boss, and eat the swipe. Then you can call in the rest of your raid and kill him.
We did the fight with no tank, 7 DPS, most of whom were ranged, movement-friendly specs, and 1 Healer and just barely got him.
So while he is certainly killable, I think he's probably got some balancing coming his way in the future.
