In my game I've been effectively blocking the Atlantic whilst focussing on the east. Russia is slowly caving, but in the meantime Britain has 60-70% rebel alignment, can they have a rebel event to force them to quit?
It is not useful at all. The game should give AI bonuses, cheats, to help it withthe issue, but to remove part of thegame because ai cant handle it even when human is leading gbr is not ok.
