5x sham can do the 2nd bitch in mech w/ 5 fire ele's and hero popped. 5x Fire ele + hero = easymode for botanica as well for the demon boss. I'll keep track of what I do w/ my 5 shaman and post strategies as I go... I'll start a post when I get home from work in about 4hrs lol^^. To answer the why would 5x sham do better than tank healer... You have 3 dpsers I have 5.. I also have 5 elementals that can tank for me, and 5 people who can heal.
