Having the villages automatically respawn fuling would be a good addition, of course make it so that there's a condition for them to respawn. Such as some other type of fuling totem, one that's like a ward in the sense that you can place it and if it's in an area of a village, it classifies that village as eligible to respawn fulings in it. So you have the choice to either destroy it, or leave it and let enemies respawn back over time.

Or just add some sort of ward that does the opposite, and when placed in the vicinity of a village, it stops any spawns happening in it. Of course, specifically, enemies that would spawn in the village, and not natural spawns.
