Don't you wish that in a defense your hero could use it's ability? The archer queen disappears and continues to fight with her fellow archers, the barbarian king gets stronger, regains some health, and calls barbarians to fight with him. I know this could be confusing in the programming of the game, but it would make things more interesting. I'm not exactly sure when the hero would use its power, maybe for the barbarian king after he loses some health. For the archer queen when she is surrounded by troops. It would be easier for your defense to win and would be very effective in war. I this would get people to strategize more on where their heroes are placed and how to attack. Please comment on how you feel about this idea.
