As a healer, I have little tolerance for hot-dogging, meathead tanks who take off in sub-50 dungeons thinking they're Superman, Leeroying their way past enemies, and thinking I'm going to heal them through 15-20 monsters (all of you clowns in Dzemael Darkhold know who you are). I have even less tolerance for tanks who run off at the mouth after they get people killed with this nonsense.
