they cost a lot and thats fine, they are important and are game changers. but with the increased AI of wall breakers they will be more vulnerable then ever. im suggesting that you should be able to use elixer or gold to upgrade walls. i think this will make the game more balanced and the thought of upgrading your walls does not seem nearly as impossible. \
there would just be 2 upgrade options, same price but one would use elixer and the other gold.
