With ally you mean coalition partner, right? And not the traditional FoG2-type ally?
Thanks for thoughts Karvon. However, requiring neighbouring satrapies would make coalitions too limited in my view.
And you can't in any event really attack people on the other side of the map, whether as attacker or aiding coalition partner, only aid in the attack of one of your coalition partners. So you can't gain control over a faraway satrapy. (Apologies for the semantics.
