The wild untameable and very dangerous living lands, seem very safe with no enemy respawns, maybe this should be a feature for easy mode and regular enemy respawns for normal and higher difficulty?

I don't have the game but I heard about this. I understand more unique enemies/story bosses or maybe if there are quest bandit camps that you clear out, why those would not respawn.

But do general world creatures or more random population enemies not respawn either?

Anyway, perhaps one could make an option that's only available after having beaten the story once. So a 2nd playthrough you could toggle a respawn on/off if you wished.
