What I do find a benefit of a pool systemConferences are unnecessary anyway. Clubs already play their main rivals twice but some others just once. Just keep it as a 18/20/22/24 team comp with one ladder and creatively “double up” the big match ups like we already do.
No need to overcomplicate it, it’s not like it’s currently a full home & away completely “fair” system.
The teams you play in the opposite pool can have a home / away arrangement over 2 seasons
Todays format it never happens
