All to many times my healers will be doing great and healing the troops I want them to and then all of a sudden a hero comes within range and bam. healer(s) start healing the hero. My giant's or wizards die because they are not being healed anymore and then the hero die's because the healing is only 50%.
Personally I would like it if healers either took a low priority on hero's(Only heal if its the last troop) or don't heal them at all.
