Allow "scrimmage" matches against clan mates.

I think there should be a mode to scrimmage attack members of your clan. Basically as a way to test base layouts against different army compositions AND allow players to develop and test different attack strategies. Players can attack clan mates and not gain any loot from the raid, likewise defending player wouldn't lose loot. The only thing lost would be the resources spent to train the attacking players army. Would also allow for friendly competition within clans.

I've always liked this idea. At the very least provide a way to test your base against a selection of troops and have the AI attack.
