The weapons include a damage multiplier system that allows you to modify every simple weapon's damage by a percentage. (200% damage, or 50% damage, depending on your preference.) So complaining about weapons not dealing enough damage or dealing too much is pretty stupid imo, since you can just change it in-game.
Unless you're complaining about the weapon balance where the snipers are not OP compared to other weapons; in which case, eat a hamburger.
