Seriously, stop it. Once you have 6 healers in a 10 man group it's no longer fun. Full duration WSG where literally nothing happened. Just 2 teams holding flags one not having enough DPS to kill the enemy FC (Horde - my team) and the other(Alliance) was unable to kill the enemy FC cause it turns out spam healing can beat the damage debuff of the FC.
Seriously, picking lint from my bellybutton is more interesting than healer stack BGs.
