You are arbitrarily applying rules to a public system that was only created to assist with grouping. Lower skilled players don't have the same vanity that a higher skilled player can have. Obviously lower skilled players would seek out higher skilled players to help or learn from. Why would you tell a lower skilled player to go play with lower skilled players? There's only so many people who are higher on the totem pole. The further you go, the less people you have to play with/befriend/enjoy the game with.
