yea I agree
with smoke-and-mirrors we can kind of simulate a surrogate suppression. but we will never be able to
actually suppress anyone in this game. The reason why can not do that, is because dice didn't intend for BF2 to be that kind of a game. We lack the core mechanics for it, like the deviation affect like you said, or triggering certain animations based on suppression, or changing the audio or manipulate your vision in other ways than just desaturation/blur filter, change your movement or controls, reduce your FoV (tunnelvision), blur out evrything except where the shooter is shooting from, simulate adrenaline rush, make you pass out in fear!... any one of these would be a good tool (except the passing out, I would alt+F4 if that happened), we lack all of them.
Mods have the power of suggestion though, the meta-game that comes with most mods (be it realism, zombies or WW2) is a powerful suggestive "feature" indeed, and Im quite certain people can pretend to be suppressed (maybe in PR, maybe in FH2), almost to the point of actually being a little scared.
But I suspect it is all in their head, and it is not an actual game mechanic. What I believe they are doing, is
waiting, for the suppression effect to go away. Throwing in a little role-playing to cover up what the game lacks.
So what it results in almost, is a trading game: bullets for waiting. I shoot you, you wait. You shoot me, I wait.
That works fine as a kind of
pacemaker for pacing if you want (lame, yea I know..), a way to slow down the game a bit by making eachother wait. but is it really
suppression? You tell me... maybe it is.
One thing though... if you're running... say up Omaha Beach.. would suppression work? Feels like it would need to have a reversed effect if you are running and are out in the open. You wouldn't cuddle up all small and scared then, you would get a super adrenaline rush and run faster and be fearless until you get to cover... anti-suppressed.
I don't know how the game would know this, perhaps raycast around you and if you don't have any cover within X meters, boost your speed up and make your vision more clear/contrasted/tunnel vision.
"Also, making a harder-hitting impact sound for bullets will make them quite aware of close-hits making them even more anxious" < doable, and a good idea
