I do him 5x a day with my shaman, died a total of 5 times at the beginning. What I do is use 1 earth and 1 fire ele and by the time I do all 5 I've used all 10 cooldowns. I always wait for my EM cooldown before doing the next one. I use drums and heroism at the start. He usually dies just before heroism is done and sometimes my earth ele is alive and sometimes not.

What sucks about it all is the repeating useless trinkets that drop and the low drop rate of brewfest mounts. Out of 13 attempts (5 me, 5 Bayag, and my 3 other 70's) there was 1 pipe, 2 hops a whole lotta melee trinkets, a couple tanking trinkets, 1 dagger (d/e'able) and finally one kodo dropped on my 12th run.
