If, as Melbourne Boy has said, 'last year the top 6 in Div 1 were equal to the bottom 4 in Champ, and that's without even recruiting anyone', then would the promotion of teams into Champ raise the level of the league?
Obviously it does little immediately to close the game between the top 4 and the bottom 4, but sticking to the status quo doesn't exactly do anything to change that either.
In addition to that, rosters for the promoted teams would not be finalised yet. So really, nobody on here is in a position to say anything about the quality of the new teams entering next season and how they will stack up against the others.
