For future upgrades, can we put more intelligence on the troops when they attack. I have observed some dumb actions by the troops:
1. Archers, barb and giants continue to attack walls even if there is already a passage.
2. Healers would heal "full health" individual troops (archer or barb) rather than heroes or higher value troops (golem, wiz, giants) that are in groups.
3. AQ and BK attacks walls rather than nearby structures
