I’m not sure if the auto aim is a feature that will stay in the game or not. It does add fun aspects to the game. For instance, when an opponent uses their cav as a screen you can respond by attacking the cav or splitting your archers.
Once I killed the enemy general when he chased my cavalry. His archers shot at my cav and hit their own general, lowering moral with friendly fire.
As far as strategy goes you must use every feature or bug to your advantage. Sun Tzu said to make many calculations.
