I think the whole notion of F2P needs to reworked. You can kill stuff fine with nothing in PS2, but to specialize to any extent you will probably want to spend cash. I am totally fine with this, but I understand if people are not, since it really does go against the game's marketing.
My only gripe is that everything is stupid expensive. For 10 euros in Tribes you could get a lot of stuff, here it gets you a weapon and a half..
