re: To anyone who's played The Division

In campaign mode, I can usually take down the boss's lackeys without much trouble, but the boss himself has been a pain in the arse (in later levels, anyway). This one boss I'm currently struggling with, if I get too close, I may land a few shots, but then he'll unload his blowtorch on me. I'm not in front of the game right now, but I'm just curious if a shotgun will stun him enough where I could continuously fire at him 'til he wears down. If so, I guess I'll pull the trigger and buy one (they're not cheap, so I wanna make sure it's useful before purchasing)...it causes way more damage than the weapons I use, but again, I'm concerned about accuracy...
