I think the barbarian king and archer queen should heal during battle. If they are not under attack they will slowly regenerate there health, but it wouldn't hundred percent heal them just 10 percent heal them and it would be very slowly. This would come in handy if you already destroyed all of the defenses and are just cleaning up the rest of the base your hero would slowly heal and cut some healing time so you could go to your next attack. When heroes are in your village they heal because they are not under attack and the same thing should happen if they are not under attack and just trying to break through a wall. they will only start to heal when there ability is activated ( lvl 1-4 heroes will not have the ability).
I also think heroes should also be able to spawn there troops like when they use there ability 4 or 5 barbarians or archers would be spawned but for defense of your base. There might also be a small ring ( like the red ring around the mortar) were there would be rage for the barbarian like his ability but it would stay in the area his shrine is in.
It would only be activated when the enemy's troops enter the barbarian kings circle of attack and his barbarian people come out. It would only last 10 seconds.
The archer queen would have the rage ability too and spawn 4-5 archers to defend with her. The rage would be the same as everything i wrote in the last part.
comment what you think and if there should be any changes or additions.
