From the results of the Poll ( https://alliancesatwar.com/poll/59/Tribes_reconfiguration_Poll ), as well as player sentiment, it has been decided to reconfigure alliances to SIX tribes maximum.
What will change:
Tribes per alliance 8 -> 6
Thievery & Magic output capability will increase proportionally. Attacker war damage will also increase.
Other miscellaneous tweaks to be announced later.
Please read upcoming Age 116 Changes carefully.
