Deployment Before Battle
Taking this from the Total War series. Before battle, there should be a period where both armies are allowed to select their units and assign numbers to them with the ctrl+number option. During this time, there should also be an area where they can move their units around and deploy them. Once each army is ready they can click the "Start Battle" button to begin the battle. I'm tired of having my army thrown into a mass and have the units get all confused trying to move away from each other in the maze of bodies. Give me time to set up for battle first. I crush these AI armies easily, but it's annoying when I'm still just trying to move my army apart and they're attacking me already.
