so all week ive found myself doing fail heroics and maybe every 8th heroic group ive entered actually has a capable tank and healer. but 1 reoccuring theme seems to be happening. tanks are kiling them selves with taunting. ill give a few mechanics. 1st boss in grim batol. NEVER taunt the malignant trogg. kill him away from the group and kill the rest. BRC 3rd boss, the fire sprites. NEVER TAUNT THEM. a smart group will lead them out of the middle circle and kill them on the outside..unless you are going for as many stacks as possible.
