As a tank, I'm not comfortable with large pulls, especially if I don't know the dungeon. However I go at a pace I'm comfortable with. BLM is my main dps, and as a job that's capable of aoe, I very much appreciate large pulls. I won't force a tank to speedun, but I will groan to myself if a tank is only taking 1 group at a time in a dungeon everyone heavily outgears.
