Well, I have an idea for wall building. Its raw, I just made this, but I will tell: Well, taking and maintaining an enemy base was, for me, a bit hard job on AoK, because, if the city is walled, OR you build around ALL the enemy wall left, OR you destroy every wall section, because, if you want to fortify your city only building in the spaces left, the enemy can simple delete his own wall to attack your new city. Then I thinked about an "Wall radius" around the Town Center. When you destroy an enemy Town Center, and build an Town Center of your own, all the walls inside an radius around the Town Center will convert to yours, for re-building the city defenses will be an easier task. Any opinion, post here, and we will try to make this idea better, or, if is bad, discard it. =)
