Did this fight tonight and was a lot of fun!
Setup:
Fury Warrior
Prot Paladin
6 DPS, 3 Healers.
I main tanked the boss as fury and even in zerker stance, getting misdirects and getting hit or crit down to 1 hitpoint (because of the bile-o-tron bot) every 5 seconds from the boss' melee swings. (hello ragebar :D)
My Prot Paladin would taunt (without righteous fury up) a second or two after the boss got the double attack buff. (i think the buff is like an 'on next swing' type of thing. this is why he delayed it so that i would rip aggro right back off after he took the hit)
Very fast fight! we were kind of sloppy at the end, but we are definitely going to do this fight like this from now on.

PoV of a Mage DPS guildie. (he dies lol! he thought the phase2 was at 25%)
