Never really thought about it, but I've sat and thought something was really weird about the game: There's no idle sway on anything, except for snipers. If that was patched into the game, that would create balance, without really having to change damages on anything. The M4 from CoD4 would've been extremely OP, had it not been for idle sway, but because of it, it was fine the way it was, though it was easy to use. That's all the weapon balance needs added, and it would be tuned perfectly.
