Seeing how there's currently 16 teams in B, why not move the top B teams up to A? I've subbed for/played against a majority of the teams in B at some point and DC, Donkey Punch, and Always Balls Deep should be in A. Some of the people who ref probably know of a few more teams that could move up as well.
I'd like to see the divisions more even in terms of number of teams, and playing mostly in A the past few years it'd be nice to see the top B teams move up rather than be the #1 or #2 B team every year
