If you were to change the number of trophies needed to join your alliance after your alliance/team is already established and there were team members who hadn’t met that trophy requirement yet (200) what would happen to those established alliance members?
I’m sure to be corrected if wrong but I believe that that person would be fine. The cup limit would only effect people trying to enter the aliance.
Nothing happens to existing players. It will be a requirement for any new players who would like to join your alliance.
