Suppression needs changed

The current state of suppression is both useless and inconsistent. I completed the challenge to get 300 suppressed targets but it was a nightmare. I had to purposefully miss my targets in order to attempt to suppress them, and a lot of the time it didn't work at all. There seems to be a minimum range to suppression, and maybe an internal cooldown on the application per target? I couldn't pinpoint what exactly was going on, but it feels really bad. In a lot of cases I unloaded 50 to a whole 100 round LMG magazine at the target and didn't get a suppression update, despite hitting the target multiple times with said magazine. 

That brings up another issue, hitting targets should count for applications of the suppression effect. It is ridiculous that I had to TRY to not kill my targets in order to get the updates for this challenge. I should never be asked to NOT kill my targets.        

Lastly, suppression as it exists in the game is useless. There should be an actual impact on accuracy and ability to aim at a target when suppressed. It is BEYOND frustrating that I can "suppress" a sniper (when it properly applies the effect) and they can just look right at me and snipe me in the face despite being "suppressed".         

I love LMGs, please make their main mechanic not terrible.
