I want to expand my vision:
Imagine that you have your main castle with trillions of flame archers. In case of massive attack you can configure the defense in a better way even if you are not online, for example, which throne room you are going to apply, each attack will be defended by 1 million archers of flame and to which troop type you will apply sacrifice. But the defense does have to give if or yes, it is absurd and very unreal to think that you attack a castle with trillions of troops and that they all hide without effect.
At the same time, example 5 million troop in maximum castle level construction,can sheltered and hidden in the castle. The rest will end up dying if they continue and follow the attacks.
Remember is a war game and the troops, rebuild very easely.
Hope anyone can hear me, the game will be more adictive.
