The "newbs", as it were, flocking to humans over aliens is a trend that most people I know recognized a few years ago in 1.1. It's given that newer players will (most of the time) chose humans over aliens, creating what can become (but perhaps, is not inherently,) a relatively large skill imbalance. While public statistics are a fantastic way to address balance, statistics are biased by the interviewees, who are, in this case, the general public. I think that some stats based on competitive clan-play, which I've heard is starting to move over to 1.2, would be both interesting and helpful, as I'm sure Norf & Co. want to cater not only to the masses, but also to the more exclusive and hard core clan-scene. After all, if not for some of the oldest and clan-oriented players, I think Tremulous would have been abandoned already.
