One problem is some maps open up in such a way that snipers can cover every entry point and makes the game just kind of dumb. They don't need to be nerfed or anything. It should be 1 shot headshot. But it really shouldn't be so easy to aim. I think it should be halo sniper. No aim assist, smaller recoil to balance. Or maybe while sniping, increase damage received. Simply decreasing ammo would help as well.
