I recently started a thread in suggestions for an AI Overhaul for NPC's, which covers most of the basic commands and expands upon them. Suggestions and fixes on the order of a Settlement System patch that is for every mode of gameplay (solo, pvp, rp, pve).
Regardless of which mode you play, everyone wants to see more than brain dead zombies standing still and slowly eating at your food supply. Expanding the usability of our thralls would be excellent since they are working on a siege mechanics overhaul in the near future, and we definitely need better guards.
