have u thought of a system of auto match making?
even in the beginning we could be auto matched only vs 6 players of similar level based on a hidden match making rating ( derived from previous leagues and current gear level ) , and afterwards auto matching with the closest players within the +/- xxx points threshold, both better and worse, if possible.
this way we could all get more balanced games, without the need for more divisions in the league.
I'm pretty sure that in all the games with elo system the match making is automatic, but the player base is usually bigger.
I think the d3cl judges could choose an approximate hidden MMR even for newer players, based on gear.
