Scouting question

[Avalon®]

Accompanying a high att hero on a scout mission will enable ur scouts to kill more enemy scouts if the gates are opened. One of my alliance member scouted another guy with 100k scouts accompanied with a att hero and he managed to kill 70k of his opponent scouts (all of them) with only 30k casualties. The reason why this is possible is because the hero chosen by the system for anti-scouting is the current mayor which the player had appointed, which is for most ppl a politics hero. Sadly the report was deleted so i can't show it.
