This is stupid. It really isnt that hard to kill someone with a shotgun.
A) dont get up in their face. Its your fault if you see someone with a Remington and think its a great idea to charge him all gung-ho thinking youre going to be a hero.
B) I kill shotgunners up close all the time. Circle around them, they essentially need to ADS to get a kill, while you do not, i cant tell you how many times ive circled a guy with a remington using a MSNC and just hip firing. problem solved.
C)Shotguns are shotguns. They are meant to be close range shredders. Suck it up.
