I generally aim to have the dungeon cleared before the healer has time to formulate an opinion about me. Ideally, they should still be too engrossed in their TV show to notice.

I wish I had a gil every time I saw these "Dear tank, why does this dungeon run not play out exactly the way I envisioned it my head" threads. You can't tank without generating aggro. Let experience, not opinion, be your guide. #backseattanking
