The problem is there is no Suppression in BFV

Yes, there is. It delays health regen, spots people on the minimap and increases recoil.

some screen blur does not slow or stop a Sniper or medic from killing you instantly on your bipod

No, but you shooting your pin-point accurate MG into their face does when they decide to peak out of cover. Or your Recon and Medic shooting them in the face does.

And you are already 3D spotted when someone looks at you for .5 seconds

... No. There is no 3D spotting in the game at all. What you're talking about is a marker that just shows the player aiming at them what class they are. It's not visible to the entire team. The only spotting in BFV is minimap spotting.
