Yep, you're going to have a lot of AFKs in July/August. It would be better to start in April imo. It gives to the captains enough time to build a team. The only issue I see is about the NWFL going on. In one month, the groupstage of the NWFL will be over meaning only few teams will remain, so for the players who are both in their Nation selection and NWFL team, they're gonna have 2 officials matches by week, which is still fine.
I'm afraid we lose the hype if we start in June.
