I watched a player extending the limits of his territory by building a structure just at the edge of it, then using the extended territory influence of that structure to create more structures and so on.
I tried to experiment on it (see attachment), and this is what I think: On one side, it seems to make the idea of Territory Boundaries meaningless. On the other, it has some risk factors to be pulled off effectively.
My question is: Is this a bug that needs to be fixed, or is it an acceptable mechanic?
