I clearly play a lot more than you. Shoulder charging is not an issue. I use shotguns as much as anyone. Unless yours is utter crap, they're still plenty lethal. More than enough to shut down shoulder chargers. Hell, I've shut them down with fusion rifles. If they kill you, it's your fault. Simple as that. It's not gimmicky like other abilities. And for Christ's sake, throwing knives are easy as hell to get precision hits with. They [i]track[/i], on top of high aim assist.
