This probably isn’t a problem for big alliances, but for smaller ones its very frustrating to constantly have people join and leave next second when they see you are not the strongest alliance or a spot opens up in a bigger one.
Im not saying you should prevent people from leaving completely, but i think its fair to set a timer of half a day or even a day, so those players can actually see the alliance in action, and meet the members, and after that if they still want to leave, go ahead.
All I’d like is for a chance to be there for the smaller alliances.
