Idea: teams are split into 2 groups(1 group of 5 and 1 group of 6).If you place at the bottom 2 of your group you can compete in a short double elimination bracket for a chance to earn a spot if playoffs,
What this means: Teams will have to play less matches which will reduce the amount of burnout for players. If you are placed in a stacked group you still have a chance to make playoffs by facing against worser teams. This also rewards teams who play good as they can take a break when the bottom 4 teams play.
This isn't perfect but this is just my idea of the IL's.
