you just have to hold asdf and click outside of the window to get auto shoot. Best if you stagger the shots so its a constant wall.
To turn off auto-shoot click inside game and press asdf.
Also to those who say that your guys do not attack the enemy when you are at their tower is completely false. Your men will attack them, however it divids the attack in half with each thing there getting half the attack, more enemy units equal less dmg. more friendly units equal more dmg. Hopes that helps
