With the copious amount of nerfs that the shotguns have been subjected to,and the absurdity which is that of Auto-Armor;while using a shotgun at this point in time (note:This predicament hasn't always existed),it's quite common now, to lose most of your gun fights, as your consistently getting a copious amount of hitmarkers. In my opinion, you guys have handled the shotguns improperly. Shotguns are no longer a viable choice at this point in time, due to the various reasons stated.
On the contrary, in reference to the perk "Auto-Armor". In my opinion, it's very problamatic in a game when nearly every player you encounter has a particular perk equipped, due to that particular perk being deemed a "necessity".
