Obviously not everyone will return, does this mean our ranks will be higher making us better players? How will it work?
I'd say that they'll be fairly similar as those who won't return would've been the very lower rankings.
That means the people in the middle of the ranks will be shit now and the people at the top will be even better.
When the competition starts up again, anyone who hasn't returned will just have accounts created for them. They'll be eligible to play as well as long as they've signed S8 contracts.
All teams have enough players because no-one is actually losing any players. Even if they don't come back they're still available as they've signed S8 contracts.
We could just finish S8 based on the signed players that were there previously. After the season we'd have a better idea of how many members actually returned for good.
