Thumbs down for restrictions on who can recruit - it just doesn't seem to add anything, and seems somewhat unrealistic.
Thumbs up on the recruitment tax. After all, the center was built and upgraded using your own gold, you pay maintenance, your peasants get recruited, and what do you personally get in return? Well, unless you are recruiting your own men, exactly nothing! Sure, it benefits the realm, but not all characters are motivated that way.
I would imagine that the tax would be within a percentage range, so the more expensive units would have a chance to generate a larger maximum amount of gold. Would make for some nice opportunities and conflicts!
