Please fix suppression it doesn’t work and the challenge takes forever

Suppression is absolutely terrible in the game. It does not work.  Not to mention the challenge for suppression is going to take forever. I played 10+ games yesterday and only got 25 suppression progress. Also a sniper shouldn’t be able to shoot and kill me if I’m using an LmG to suppress them. Literally shooting at them/next to them. Please fix the suppression so actually does something and fix the challenge.
