Concerning how prisons work I think there isn't much wrong with how things work now.
But perhaps it should be possible to ban anyone ending up in your prison.
If someone breaks your law repeatedly and its in your realms culture considered a serious crime, you should be able to execute him.
On infils i think it certainly is fun to put a sort of newbie layer into this class or perhaps even the others where you have the option to do these low risk low effect missions to learn the tricks while playing the game instead of siting in a city for months hiting the same button.
