If you think this is gonna work with this community or any other you're dreaming.
I personally could give two craps about someones DPS in a dungeon or trial or what ever easy-sleep induced content we do.
But when we lack the DPS on a extreme fight or end game content, i honestly often do not need a parser to see who's lacking.

Sure it'll help but it will do more bad than good. People will start to bitch more and more at little stupid stuff.
