defence, mortar, cannons, wizard and archer towers improved.
i sometimes find that when under attack, and a large group of troops are attacking something like a town hall for example, my defences are firing at a few lesser targets like a barracks of wall, can they programmed to fire against the attackers of more valuable buildings? may be by having a general to co ordinate the attack? or it could be an upgrade to the barbarian king to act as a general and then you can control the defences manually n switch to each type of your defence and then aim it yourself at the attackers it may add more depth to the gameplay aswell just an idea i had.
