I believe that the mentor system should have a daily or weekly requirement to keep your crown on your head. It is a system that easily gives the ability to mentor people based on just playing the game. You don't really need to go out there to be a mentor. Just play the game and eventually you are a mentor with out aiming for it. There should be something that should set good mentors from bad ones. The ones who want to mentor and the ones who only want the crown on their head.
