Do you have no pride, turncoat? Trade her with somebody who is DC but has EP girlfriend.
So, I play primarily with my other half, Shes with DC and im EP, how ever when we made our characters I didnt notice that we were on different teams. So now ive sunk aload of crowns on upgrading my horse only now to realise that I CANT EVEN PLAY WITH HER. is there any way to change alliances even once or once per 7 days running of the war so that I dont have to make another sodding character and lose the upgraded horse.
