Personally I think when your army camp is filled and someone raids you the troops that you have trained should attack the opponents. I think this would be so op but to balance it out they can improve the amount of loot you get. Let's say there's a base that has their collectors or storages out and there maxed 8 mill in each. The attacker should get lets say like 1mill of each because the troops that the opponent is using will be attacked by the defender by his troops so that should balance it out.
