Completely left untouched, SMGs aren't one shotting you either.
hate to differ but yes they are...
You're wrong, sorry.
ok so you were playing the game i was and you saw that i'm wrong...genuis...im just expressing a fact, period.
"I did poorly with a weapon, therefor the weapon must have been nerfed."
You're wrong and anyone can see that, even without looking at the games you played. You did poorly with a gun and so you came on here to present your stupid line of reasoning. There have been official patch notes stating what was touched and LMGs weren't on the list.
Suck it up, play better and quit whining. The fact that you played poorly isn't the guns fault.
