Troops left on map after victory
We all know everyone wants to get troops back that survive an attack. A little addition to this should be that troops left on the map after 100% destruction should be able to disperse on the map to remove trees, bushes, mushrooms, and even gem boxes, and collect the gems at the same rate that they are collected when the user removes them from their village. The items could have hit points that correlate to the amount of time and elixer it takes for them to be removed, normally. Obviously the hitpoints wouldn't be as high as a building but it could be relatively high and maybe take a small group of barbs a good few seconds or so to remove a large tree. Maybe giants go after the big rocks as if they were defensive structures or something while the goblins search for gem boxes, everyone else just searches for the closest item. Could be neat.
