Heh, VC spent weeks calcuating the weapon spreads from GE007 and balancing weapons against each other, and we did a lot of playtesting with them. Of course the beta isn't perfect, and we will continue to improve stuff, but I would recommend playing the game for more than a day before coming to a conclusion that the weapons are horribly skewed. We think they are pretty good, and they will get better, but take some time to really play with them before coming to a conclusion.
Personally I'll take an AR33, Phantom, or RCP 90 against a guy with a PP7 any day.
