I don't even feel the need to defend myself here, it's blatantly obvious.

No, they're not

No they are not. I dont see any issues with the shotguns.

Yes and No, the gun itself isnt, but C3 has this new "feature," in C2 when you were shot, you would stop running, but in C3 , you run at people while getting shot to close the gap of the shotguns range.

Guaranteed if equipping a shotgun made you stagger when shot , it would render the shotgun instantly useless.

The gun itself isn't overpowered, the exploit is.

well, i voted "yes". but i think they seem OPed because the aim or the recoil of assault rifles are far different then in c2, while shotguns seem to be the same.
