I am not talking about scouting, I am talking about spying, this rule prohibits to being a spy on two alliances . But, as I told you, this is not the real issue. It's about playing as a family and not being able to check our villages when needed. The same issue is relevant for friends too. Being on other location on map creates a need for other alliance, otherwise, it is not possible to survive.
lets say there are different opinions about it and many enjoy game more this way. How confederacy system stops you from spying, exactly?
