What you are referring to is, when archers stand on the wall and shoot at incoming enemies. An archer cannot see what he is hitting behind the wall if he is standing on the ground. He shoots blindly and hope that one of his arrows hit something. That goes the same with artillery.. How can they see whats behind a tall wall?? And yeah id like to fight against your level 8 wall.
But what i meant was. Whats the point of having hem when only archers and arillery can shoot. I didnt say whats the point of having walls when you get attacked by horses and soldiers, but archers.. Cause they can shoot above. / over walls. Get it?
