Yes, sniper should be nerfed so hard. He is the only class, that has no range damage limit, and i think it should deal less damage at close range. Their "skill" quickscope headshots are op, instantly reloading so fast a sniper riffle and dealing 150 damage at ANY range. Also its impossible to waste all your ammo as a sniper, it has huge 25 ammo on clip.
And we all know that after Heavy update the sniper class will be nerfed so hard, and you can't do anything with it, this is unavoidable, accept it already. Entire community will be in heaven after that.
