What do you want from your tank in a dungeon?

[Bombast]

I have been asking my PUGs if they want experience points, treasure or quick runs. Out of the last ~80 dungeons I have ran, I have only received a response twice. Once for exp, once for a quick run. Should I keep asking? I had assumed people would want a say, but apparently not?

I HATE this. No one ever responds, so I default to a quick run. And without fail, the lowest level person always starts pulling the extra adds for XP, usually causing a near/actual wipe.

Makes me want to become a total dick in this game. Every time I try to be nice I get spit on, and any time I have even a slight blow up, I get 7 commendations. Its like everyone is trying to train me to play like an ass.
