Would love for a balloon hero to be created, perhaps dropping a string of parachuting wallbreakers into bases as it flies over, releasing wallbreakers in increasing volumes the more it's upgraded.
It would be fun to hear the Wallbreakers going ' Weeeeeee !.... Boom ! ' as they are released within boundaries of bases, taking out internal walls.
For defence they could take out archers that sit just out of reach of cannons, archer towers etc
