Why not just add some BP incentive to the less played side.
Don't really understand why bhvr hasn't tried this solution. Unless they have some data to indicate that more BP incentives don't work. It seems like it'd be a pretty simple solution to a couple problems right now.
1; The grind in this game is agonizing particularly for newer players
2; It would be nice to be able to complete all the surv archives within my lifetime.
Seriously go crazy. Give the underplayed side 100%, 200%, 300%, a new perk for free every game idc. BP is capped at 1mil so it's not like older players would save up some exorbitant amount of BP.
I do understand that bhvr may see this as a bandaid instead of a permanent solution and I guess it kind of is. Band-aids are meant to be removed when the wound heals though.
