I've noticed in a couple of recent campaigns that one-settlement nations are able to put up a frustrating level of resistance. At an early stage of a game as Macedon, I'm seeing many nations with two full stack armies, sometimes with an additional two appearing when I move to lay siege to the town.

These giant armies are then proceeding to kick my much smaller full-stack force in the face. I must admit that I find this pairing of dynamics extremely frustrating, as it makes the game both unrealistic and so slow.

Does anyone have any thoughts on this?
