So for watching what strats, and reading up on him, with no mention of an enrage timer, my guild thought we would have some fun and try him tonight. A half dozen wipes later we decide to 3 heal it, so our comp became 2/3/5, and it seemed to go well, really well. The fight was moving smoothly, not a single missed shockwave dodge, and then, it happened.....It turned red. the DH tank goes down, I move to pick up the boss. Rebirth goes out, but the DH waits because shockwave is about to happen, Defensive CDs get popped, adds are dead, DH back up and tanking. Arcanoslash happens, DH dies again, I move to pick up boss again. Arcanoslash, I'm dead, raid dies. DBM reports that combat ended at just over 9.5 minuets at 24% health
