Rias is a very good King but for that very reason the match with Issei could be use as a way to show Issei growth as a King. Becuase If beats a King that is known to bring out the best in her servants it will show how Issei's leadership skills have improved. What I have read of the LIght Novels Issei needs to beat somebody who is known to be a much better King then he is.
