Wall Breakers become a valuable CC troop
The worst CC troop today is the wall breaker. It comes out and blows itself on a troop but can't kill even a barbarian the same level. Wall breakers are the most expensive troop yet fails do anything. You change the AI of the Wall breaker to Target golums only and let them do 40x damage like they do against walls. This can give a twist to the high level and war strategy. Give your ideas how to tweak or improve this idea. Ps Golums are basically walking walls.
Edit: make them immune to poison spells since they are skeletons.
