Attacked While Sleeping

Call of War can be very fun at times, but it is extremely frustrating at others. I have countlessly fallen victim to spending hours on a game to be attacked in the middle of the night whilst I'm sleeping only to wake up to large portion of my army obliterated. The biggest flaw of this game is that every player is human. Everyone must sleep unless you're an unhealthy nerd. There needs to be some kind of change to this.
