Please add Suppression mechanic back

I just noticed there is no suppression in this game anymore. I don't understand why it was even removed in the first place, there was no problem with the mechanic itself.

Suppression is great. It makes the quick TTK feel more balanced IMO. If I get the first shot on someone but misses by a hair, right now it´s over for me. With suppression, that guy will have a bit harder to aim and so I have a chance to recover, get another shot or run to cover.

As it is now, if people get shot at they will probably just shoot back. If they got suppressed that would be a harder decision, stay and shot and maybe miss, or run for cover, waiting for a better opportunity.

Has suppression been removed? In co-op I get suppressed all the time if I decide to aggro a horde of bots
