I feel that there should be more positions like Stewards that will enable knights to do more stuff.. Perhaps a Chancellor? Chaplain? Champion?
they should be like Stewards and not show up in titles to prevent people from having a whole page of titles
Small things like those really makes knights feel appreciated
I would also commend Perdan on their system of army promotions, it really feels like you are progressing somewhere and you are not just stuck there as a knight and that your efforts are actually noticed.
