I would be ok with a personal dps meter, one that shows your own dps, and possibly one that says the value that is highest in the party and possibly the average, but no names. This will allow players to improve, give them helpful information without giving players the oppertunity to put people down over it. There is no reason for the whole party to know who is doing the least damage except to put eachother down. The problem is it's inevitable that we will see scores of "You casual scrub learn to play" otherwise.

What I want is the best of both worlds, and this idea is the best I can think of.
