You have probably experience this before. You click next turn and then paff! a combat screen appears. You do not know who from where attacked which units. You just know that there is a battle.
It would be interesting that before showing the battle screen, you can actually see the enemy unit in it's original position, then draw a a movement path between you and that unit and make the unit move on this path. When the unit has moved, the combat scren appears. You can write on the screen during the animation process "You are being attacked".
It would also be interesting that instead of just showing an X in the target square where the unit is supposed to move that you could actually see the whole movement path.
