While I agree tat qsers can be annoying , I dont think the rifle itself needs nerfed. They barely do what they are supposed to the way they are.
I was playing some tdm last night and found a nice perch with a great view of the building across the map where the enemy was hiding. I was getting almost constant views of them looking out the window and running around on a patio outside. The problem was, I was using a silencer and was getting nothing but hitmarkers. I think I got 4 kills before I ran out of ammo.
When I died I switched to my unsilenced barret and went back to the same spot. Within two or three shots I was mowed down by a barrage of across the map ar fire.
The whole point of a sniper rifle is to get one ( or two I guess ) hit kills from a safe position far away. These type of positions are hard to find, hard to get to, and usually hard to defend. I shouldnt have to go through a long process for one kill, then either have to go into hiding or run around with my secondary.
