If the move order were tweaked with, I wouldn't mind seeing an army's strategic move factored in, probably affected by survival skills vs terrain.
In the extreme case, for instance, it should be fairly hard for an army of move-1 Abysian Lava Warriors to leave a province to attack another they just overran before a Vastness or Doom Horror arrives from next door. Less extreme, Machakan spider knights in a forest should have an easier time of keeping the initiative than would their Ulm heavy infantry pursuers.
