how is it that they nerfed evety other gun but they never nerf the LMGS one i think needs nerfed is the mk48

i noticed how they have not nerfed the lmgs to me some need nerfed like the mk48 because it has like no kick and players are able to fire long distance with even with it a silencer on and still hit the target like it was nothing so to me it needs nerfed and the other ones do too
