It sucks. 1 hour of no gameplay lol
Either reduce it to say half an hour or 15m or remove it entirely and reduce the cost by half if you do this as well to immediately remove
I like the concept but it just forces people to go off the game entirely after flagged which is by far what the game wants. We want activity, if everyone gets flagged everyone goes offline. most people feel the need to fight jut because they lose hero energy anyways so why not kill a few troops with hero abilities
Onto my next suggestion: if players dont meet the required power and just bring heroes only so they can waste their enemies heroes and troops, it shouldnt count on the player who brought an armies energy. Its unfair. It wastes energy which is already something that takes too long to get
