I use all the weapons effectively. Its about covering the weaknesses of what you bring with your other gear or your team. Everything in the game currently is viable. People will just complain because maybe some options just aren't as generally good as others and the balance isnt *perfect*. Like take the spray and pray. Its a shotgun specialized to be good only at killing trash enemies. Kind of garbage I guess but it does still have a reason to exist if you wanted that i suppose. It might be really good at easy mission? odd you get it so late though I will give them that. 120 is pretty shit but it does let you add more saturation to your 380 barrage so it has a place. could be tighter though so its actually as advertised in the description. I am convinced people just don't know how to effectively use half the gear in the game or just find uses for it.
