Yeah Heyo is nice
So i'm Sentry now :-/
But yes, you should also gain ranks RP-wise. Just make it that the ranks 'till Knight are RP-wise. To become a knight, you must be in training at one or get an RP-promotion for doing something honorful. Same for Paladins, except you can't go in study at a Paladin, you need to do something good. I mean, people aren't being chosen King because they're strong!
