Hay for horses!
I'm all for upkeep removal. What I would like to see is link between regular c-rpg and strategus where you would have to own some land with grass on top of it, to be able to gather hay. Also, who ever saw some lowlife bandit having armored horse, that's for knights. And to be knight you have to be lord, to be lord means you have your own land. Same goes for metal armors and weapons (blacksmithy required), rags and leather for commoners.
In order to be archer you'll have to be part of some bandit crew which owns a Bandit Den in forest/mountain or to be part of militia (stationed in castle). Same for xbowmy old friends.
Throwers - commeners throwing only stone and cheap axes, ninjas and militia everything else.
We need feudalism in this mod, seriously!
