here are the issues ive noticed. 1) i rally on enemy town center. units will walk allll the way around the walls of the city to attack the walls which are closest to the tc. rather than attack the walls i dropped them near. the previous AI was much better. 2) drop units. rally on town center. units will attack wall. when wall is broken open they start attacking another wall peice. when that is destroyed then they will finally move towarda tc. 3) drop cavalry, drop miner to break wall open. wall is broken open units continue to attack wall and dont notice wall is broken right next to them. 4) when buildings are pushed together tightly units dont know how to walk in between them. they go far out of their way until a bigger space is available for them to walk through. 5) infantry will refuse to attack wall to get at defensive structures prefering to walk long distance to attack a farm. 6) defensive structure with little bit of walls(open on both ends) cav attack wall because farm is pushed up against wall. rather than walk around the wall they attack wall
