u should make transfer available between pvp and pve like items/tames and character. with this in mind, people wont lose everything and keep playing. also more suitable for people with jobs/school. people can play pve with disadvantages offcourse
possible mechanics:
- lower farming rates on pve
- lower character xp on pve
- lower chance on breeding mutations or no imprint on pve
- lower valuable lootcrates on pve
- some tek engrams not unlockable on pve (tek turret eg)
- wild level dino level cap on pve 120 (wyvern/drakes/reaper and so on)
i hope u get the idea!
