I really don't get this clamour for a smaller alliance cap. Putting a 50 player alliance across two separate alliances doesn't matter when they share all forums.
Cancelling shared forums removes a key aspect of this game, and it will punish rim teams more than premades, because rim teams filled with casual players don't use discord or skype like any premade will.
It just completely fails as an idea after any real thought.
The point is that with no rotation in Dom and Olympus and with now a reduced chance for rotation in wonders, there is little to no incentive to be in the second wing of that mra/two wing alliance.
The logistics of them communicating isn’t and hasn’t ever been the reason we’re advocating a low alliance cap, it’s the incentivising to fight between alliances rather than pact. It’s based off the assumption that players will play towards their own selfish ends for a win.
