There should be some way to bring mid-tier guns up a notch without making them too powerful. I just hate how guns like mp40 are useless once you spend the extra gralats for a better gun. Weapon XP system maybe? lol

anyway... the freeze on the AA12 seems a bit much. It's hard to work with in it's "comfort zone" of medium range. maybe tweak the spread as well? It just feels like the third bullet is a third wheel.
