While your idea is good, this change, in my opinion, would come with two problems:1) The lords from the Desert Borderlands have been thought to fight in their circular area, and not somewhere else (especially Rempart keep)2) Make NPCs follow a player has many times come with bugs (NPC not following anymore, teleporting or stuck in a decoration structure) Considering those 2 points, I would state that this might not be a bad idea, but it will need more work.
