I love the idea. I don't think it'll stop the arguments over stats as that'll still be available to those that want to get them, but for those of us that aren't so bothered about the small differences in damage per second it'll be a nice bit of mystery.
@memeics - I don't really see that there's a gap. Anyone into games stats can still get the info using datastorm and the like, regardless of wether they've played the game before.
