Every time I battle in clash of clans using a healer, one thing always frustrates me. When all the defenses are taken out and my healer has healed all my troops, she just keeps on attempting to heal the troops. I was thinking that it would be cool if supercell made it so that the healer becomes a dark healer (Or maybe the name destroyer would make more sense) once all troops are healed. I was thinking that she would do damage to buildings equivelent to the amount of heals done to troops (depending on the level). Anyways, thats pretty much it. I just thought it would be pretty helpful and much better than a healer with fully healed troops.
