I'm a bad player and rarely use snipers. I decided to break out an LDR with crazy perks and stats yesterday in Iron banner. I consistently got 6 to seven kills a game (I almost exclusively use primaries). One game I was just pulling up and blindly firing and I got five head shots. One of the head shots was on an a hunter who popped his super and went invisible before he came around the corner! Now with all of that being said, I do not believe they should be nerfed. Yes, it's easy to pull off crazy shots with them. But, they are also the hardest weapon to master in the game.
