Territory System, is Adjacency required?

[DarkMesa]

I would like to see a system in which the more territory your faction controls, the closer they have to be to an already controlled point. Owning a fair amount of territory will get eventually only allow you to cap adjacent points. Owning little will allow you to cap just about anywhere on the map.

This would allow you to organize more surprise style attacks in order to gain territory when your faction isn't doing so well.

I feel as though having to fight on the frontlines when you are forced back to your foothold would be rather difficult, and this would help the enemy presence feel less concentrated and potentially overwhelming.
