The upkeep idea is interesting, that alone would provide some pretty huge incentive to build more expensive castles, so you could more affordably keep garrisons available in more locations.

Only problem that I see with it though, is the sort of huge disparity in home castles, and what that would mean for research costs, as well as the fact that mage costs are relatively well balanced already, and thus it would seem to make sense to make them more expensive in that case, and that would be painful in the first year or so.


As far as defense rating, it sure would be nifty if the better defended castles had better tower defenses at least. Currently if you get 8 xbows in your towers, you get that in every fortification type that you make. This would make early kills that much more difficult, and painful, as you'd be much more likely to lose expensive sacreds or expensive leaders in the assault.
