Yeah, they need to do a lot of things like this tbh. The biggest issue that allows for hatchlings/pistolings to thrive is that the best loot in the game doesn't require gear to get. And the best way to make you want to use gear to make money without outright requiring it through shit like gearscore, is to gate it behind combat. Loot on or guarded by AI enemies, or in a location that promotes PvP like a door that sounds an alarm and takes ~90 seconds to open. Do things like this everywhere: high end scavs or raiders patrolling inside resort, at the start of labs, at techlight, have kiba set off an alarm and open the gate slower, and put better loot on higher end scavs. It incentivizes using gear without forcing you to use some just to play, because playing the way you want to is important. You're far more likely to get that good loot with a higher end kit, but you can still try it or just loot somewhere else with little to no gear. You can still hatchet run for easy money if you want, but you won't be getting those gamma-able value items anymore, leaving players with that option too.
It would be relatively easy, I know they can alter loadouts for AI on the fly, and adding entity spawns to maps and pathing in Unity is easy, unless they're using some proprietary pathing system.
The game would be so much better with incentive to run gear.
