I tried the last boss with my pally + 4 Shammy team all lvl 73. I positioned the shammies standing as close to the pally as possible so the chain heals bounce back to the shammies everytime, i also did jump/cast to reduce the debuff but once she enrages its pretty much geegee for the pally, i simply cldnt heal thru. Prolly was the Chain heal takin too long to kick in, might try with LHW after this post. Any one else has a better strat?

Im kindda gettin demoralised by all these "Anti-MB" bosses and all the "pick-up" Quests. I might just cut down to 3 or 4 box and quest
