Well we are finally working on heroic lei shi 25man, we will be 3 tanking the fight, I will be dropping stacks on the boss and then picking up the adds ( warrior tank ilv 500) , Should i be stacking a shit ton of stamina or should I go for a more mastery build? our other 2 tanks (dk and pally ) will be taking the boss. Any tips or useful info for them? Thanks for the input.
