I sure as hell know I do. For one thing, machine pistols are meant for close-quarters combat - how is a three-round burst gonna be any use in CQC, aye? For another, it's so weak - just about any time I shot someone in the campaign with it, it needed 2-3 bursts to kill 'em. And for a third, it just looks weird - like an M9 with a branch stuck on the back of it.
IW, boy oh boy, have you f***ed up this time. Does anyone else hate this disgrace to the good name of Modern Warfare? (The gun, not the blog!)
