I think arrow refilling was definitely something that needed to be removed. Simply because, with a large bag of arrows, with 68 arrows, you are doing it wrong if you use up all those arrows. I normally bait the enemy with a few arrows, and lead them into my lines of bowmen and crossbowmen, and then switch to sword and charge.
I think the idea for a fortress for each rebel faction is a good idea. Like the Welsh rebels getting a fortress, Prussians, etc, because it would be easier to remove them from the game, as well as make peace with them, if you accidently killed a few of them.
