I just don't think slapping points on suppression is the right way to tackle the issue. The problem lies with the person receiveing fire not being suppressed enough, and points can't fix that.
Well I'm suppressed enough and even when one bullet comes at me, I either head for cover, hit the deck or run the hell out of there to the closest cover.... the current suppression system, imo, works just fine as it screws up your screen and makes it difficult to see your sights clearly, not to mention the flinch jerking action that happens so often.... that person being suppressed is already at a disadvantage and if they don't get their head down, then they stand a huge chance at getting killed..... and they'd deserve it.
The only problem I see is that few people use the suppression properly to produce the above effects on a player to put them at such a disadvantage.... if you try and shoot accurately at them to kill them & save your ammo, and miss, then they're not going to be as suppressed as they would be if you spammed a bunch of rounds at the guy.
I've seen it first hand in the last couple of days playing.
On Grain Elevator as German MG, I had my team getting chewed up by marksmen in the top floor of the grain elevator.... I laid down a pile of rounds in and around the windows and they kept their heads down for a good 30 seconds.... not just from the suppression effects in the game, but also from thinking that I am still trained on the windows waiting to turn their heads into mush.... which I was.
On Fallen Fighters as the Tank Commander, I covered my team with HE rounds and MG fire towards the Russians.... and when I'd see some russians run off out in the open, I unloaded HE rounds around them and heavy MG fire to the point several dropped to prone as soon as they could.... I kept a fix on them and could see them crawling along the cover trying to relocate without me seeing them.
While all of the above was happening when I used Suppression properly, they were not a threat to anybody on my team..... if they attempted to pop out after being suppressed so heavily and fire back at myself or my team, I was ready to finish them off with direct kills.
If I see someone standing out in the open and firing back after being shot at, chances are they weren't suppressed in the first place..... thus players need more incentives to use suppression more often and properly.... in order to entice players to do this properly, they need to have some way of indicating that they've suppressed enough.
Points are one of those ways without making any drastic gameplay adjustments or adding more to the suppression system.
my opinion of course.
