People used shotguns in COD 4, a shot gun and desert eagle use to be a good class for run and gunning.
and idk about you but im glad dudes can't switch to the f**king AA-12 or spas-12.
it was this way in COD 4 And WAW and both were better than MW2.
having shotguns as primary is the best thing they couldve done.theres no disadvantage for snipers when they can switch to an aa12 and be just as deadly, if not more deadly, than you are with a ump or something. on top of the fact nothing is more annoying than unloading 3-4 bullets into someone and having them turn and hit you with the spas from 50 feet. itll be nice not to see snipers running around with only the shotgun again. now you better be nice with the pistol if your gonna camp and snipe, it balances it out.
