Mouse users destroyed blackops 4?

So BOps4 with it repley death cam, it appears as if at least half the players are using mouse and keyboard. They insta 180 and perfect aim, why sony allowes this crap to go on???

I'm gonna kill you again-and-again using my kb/m and laugh in your face.

I know right, it's almost like people are playing with higher aim sensitivity and are actually good at aiming
