Killed in cover

Why do i get killed in cover so much the kills cam shows no line of sight possible its making mockery of the game and trying to be tactical.

The snipers take full advantage of this and the embarrassingly poor sniper mechanics to just sit back all day long as well as using the drone exploit. Just don't see how this can be fun

I know the drone exploit fix is in the pipeline but how about banning the cheats who use a known exploit?
