DPS display could easily be solved with a system already in game.

I suspect you want to see everyones so you can kick people out of groups.

So what if he does? If a healer keeps letting people die to survivable things, would you not kick the healer? If the tank never picks up adds, would you not kick the tank? But if a DPS does terrible damage, it's suddenly a sin to want to kick them? There is nothing elitist about expecting people to pull their weight in a fight. If you decided you want to play DPS, your job is to do a reasonable amount of damage because bosses don't kill themselves and DPS checks permeate the game. The people you play with have a right to know if you're not doing that job. There are 7 of them and 1 of you and nobody is entitled to impose upon 7 other people to carry their dead weight if they don't want to.
