Okay, going to start this off with the fact that I hate healers. I think they are silly and they always make me mad. When people distract my archer towers with their other troops and then lay healers, and my archers just try to keep plugging arrow after arrow into the same enemy troop with no success. I think it be awesome if there were a rules engine or something in place where you could select what troops you want particular buildings to focus on. That way, if my Archer Tower is shooting some Giants and a Healer comes around, it stops shooting at the Giant, and focuses on the Healer to get that out of the way.

Thanks! Just my two cents. Not sure if it's been posted before, just wanted to throw this out there.
