I suspected this was more of a formality, as a way for leagues to show their alliances more cosmetically than Town Hall name tags.
Alina, you seemed to have confirmed that is basically what this update is, and that gameplay mechanics are not affected. That statement seems pretty clear that there are no bonuses or otherwise.
However, I do want to verify that leagues within a coalition can still attack coalition beacons and fortresses for the purposes of upgrading.
I'd like to also verify that leagues within a coalition can still issue 'friendly' challenges to each other.
Hello!
I do confirm that relationships between Leagues remain absolutely the same as they were before two Leagues joined one Coalition.
Coalitions don't influence the game mechanics between League in any way :)
