@Duplicity , i Highly doubt you will kill the boss XD but if by any means u do , u probally will get tons of rep here hehe. Maybe speccing Fury and going on tank gear, Bloodthirst + those mini victory rush triggers + crazed troll face talent (dont remember the name).
@Ghothicalchemy , i'm specced for maximum healing, i'm a WoGer , if you spec for threat you'll probally get better times like 10 or maybe even under 10 minutes ^^.
