I am attempting to take down a pretty major enemy city but i am a bit stumped. The main city of the player has 18k at's and random assortment of others, that isn't the problem though. Inside there are 9k ballistae and 1k catapults behind a relatively small force of archers and warriors and other rainbow yet they have already batted down 3 99k archer waves with relative ease. Techs between us are all the same. So i am wondering, are there any suggestions on a less costly way to kill those ballistae and catapults???
