I understand what you mean by that. You meant to say that to siege an more internal Unpeaceful Town, you must first siege the more outer layers of Unpeaceful Towns of said nation, like an larger analogy of the survivor cities of AoT. It would be a cool mechanic, with application on IRL, it would not get well accepted in the server as it's something that would require several technicalities which the server does not have not the players would allow it to have.
