Even as a tank, I get pushed for speed runs (which admittedly I like), but some people just aren't smart about it.

For example, I tanked Halitali HM in DFR the other day. Drew an obviously under geared Brd and Mnk as DPS. (a cursory look at the HP is usually enough info). Not a problem, I don't mind normal pulls. However, after the first two pulls, the Brd starts yappin about wanting bigger pulls. I just ignored them. Then we got to the first boss, which went down just fine, just extremely slowly. After which the Brd pipes up yet again: "NOW can we do larger pulls????". I finally look at him and see that he is only using a lvl44 pink bow. (!!). I finally responded to him "Why? The DPS isn't exactly over geared for the content...." Blessedly, it was the last I heard about it the entire dungeon.
