It will never happen but the AFL is truly an AFL should have less Vic sides. It is true that GC and GWS (merge with roos, dogs, saints or dees) aren't working but they like the Lions and Swans should be hybrid sides until their own local supporter base is established.
Returning to 12 sides would see an even comp with 22 rounds.
Most importantly the WAFL, SANFL and VFL would be stronger leagues with less quality players stripped from the local leagues.
I personally think the perfect balance would be
VIC - 6 teams
WA - 3 teams
SA - 2 teams
NSW - 2 teams
QLD - 2 teams
TAS - 1 team
I would however settle for
VIC - 8 teams
WA - 3 teams
SA - 2 teams
NSW - 2 teams
QLD - 2 teams
TAS - 1 team
