I like the ideas but do not want them added to the game. I have 3 places that are under assault almost all the time. They have lost the outer wall 4 or 5 times but never the inner most walls. Spain came close once as they were taking over the mid wall before route set in. If the AI can not get in now with me defending I do not need better defences. I am not very good. If only the AI got the improvements I may never take a wall again myself. As it is that 3rd wall has been the wall to far more than once. I do have 1 city that the Danes want real badly that post cannon towers has killed 8 army's so far. I think this is a problem with the AI as cannon towers reach father back than the AI sets up camp.
