Plain and simple, some of us that use PCs can use Parsers to self improve, educate ourselves about where we stand and go from there. That's all we need.

I am against in-game parsers being available because, as Yoshi stated, it would promote people going ego-trip-happy over other people based on numbers alone. "Hey, we just kicked that boss in the balls!" "Yeah but you were .0000005% below everyone else in the group so you sucked". People actually do that, so, I agree with yoshi. Never EVER allow a parser to be part of the game itself. Plenty of us have access to our own parsing software to improve where we can without having it shoved in ours or anyone else's faces the results.
