No changes to A/Masters, but some significant changes to B/U21.
B expands to 24 teams. I expect the competition will be really watered-down now, and there will be some big blowouts. Also, I think it's time to put some seeding in this competition. It's a bit farcical that 5/7 RSSL top flight teams will be in the competition this year.
No word yet on how each league will assign their additional allocations.
