The guns in DF2: JK weren't very well balanced. However I'm pretty sure the team at Raven will fix that. They are the one responsible to the great FPS games like StarTrek Voyager: Elite Forces and that other "famous gore infested game".
I mean! There has to be a limit in game violence! It's worst then seeing Keano Reeves playing a Irish-Inuit that has only one eye, one leg and doesn't speak anything but dog.
