So opening of walls most attacks funnel in only bombers will still go for walls? Is That why I see a lot of open walls upfront and double walls along the side ...attackers have a code of attack they have to follow?
It depends on some other factors - The space between a wall and a building, if that space is too little some units still will attack the walls. - The distance and the amount of hitpoins of the wall also determine wether a unit chooses to walk the extra mile or smash the wall
