I'm sure a good fps player can easily go 20 to 1 as SMG Infil. Move from cover to cover, sneak up behind enemies, aim, hold down LMB, uncloak and win. You don't even need to ads with these SMGs, it's totally unfair to sneak up and instagib players like that. Imagine how people playing on low graphics feel when they get instafarmed by something they can't see coming. Plus what is the point of fully automatic scout rifles when you can use SMGs?
