Yeah, I'm also getting the feeling SMG's are a tad bit owerpowered but since I never really was on the receiving end in real life I can't say if they are plausible or not. It's,especially dreary,when,you have to go against UK paras with German rifles, one SMG and one MG in a whole platoon like in my current Market Garden mission.
Was there ever any post from developers,about this matter?
