Agreed.
A cap will just keep things even more unbalanced
Imagine a AA with the best players of SG, or D1 or any of the big AAs left.
That alliance would win all awards.
Even more so, as they don't have to deal with inactivity.
It's better to stick with the current system.
The smaller AAs should instead look to merging into one big alliance.
Alliance based games are about adaptation.
