The more to balance the game mechanics between the AI and player the better the game will be imo. The AI will also follow the same rules as the player and will need to rest too. I think this adds a little more balancing to help the AI against the mighty player. I like my game to be immersive and one thing I didn't like was all the AI parties did somewhat simulate spending time in town while the player just pops in and out of stuff. Now you have an excuse to let your wounded heal.

With this mod installed and resting mechanic enabled you will need to actually wait in towns or on the map each day to give your marching soldiers rest.
