Walls are way too expensive to just pose as an obstacle for troops to get through, they should be equipped with special features, be it: exploding once destroyed/dispensing poison to nearby enemies/ stunning nearby troops, im new to this forum so I apologise if this idea has already been ruled out. I also suggest defense troops disguised in walls, perhaps a barbarian can emerge from a wall once its destroyed. I strongly feel that this expendature on walls is taxing and any of these features will be extremely appreciated. Sorry for the long post, no potato.
