Here are some perks that should and could easily make a return from D1 to D2 in some form -Perfect Balance We have counterbalance stock for recoil direction but this could be handling on top of the original stability increase. Say +20 to both. This would work as a perk or mod. -Third Eye This would interesting to see considering we have the radar mods and could be a nice plus for scouts going forward. -Surplus Ammo finder but on your gun basically. Probably wouldn't change much at this point considering how scavs and ammo finders are. Plus we have some other really potent ammo perks so this one wouldn't really stick out like a sore thumb, especially if what weapon's its allowed on is strongly kept in mind. -Tripod Could be adjusted to Bipod though, Tripod would be a bit much in D2. Just something I was thinking of looking at my D1 gear again
