Considering I'm finishing 5 man heroics at over 30k dps as a 450 item level tank with 450 item level weapon, I would hope that most dps are able to top that. But at the end of the day if we finish the run without wiping due to crap dps or people standing in stuff then I really don't care what they do. Of course, I also get instant queues so they're only wasting their own time when they do half the dps they should be doing. I know I can queue up and be in a new dungeon 3 seconds after I finish my current one.
