This is an old one but I have some thoughts. For a while I've had the idea that lords should be able to delegate more powers to knights with specific titles. The Steward currently controls food. Other powers could go to other roles, for example:
Region Judge: Can Hold Court
Captain of the Guard: Can recruit and disband militia
Master Mason: Can upgrade and repair fortifications possible all buildings
This would be a great way for newer players with knights to learn the ins and outs of some of the mechanics. It will drive interaction between knights and their lords, and create potential for intrigue and conflict.
