Attacking people in your clan...
I came up with this idea that I thought was cool. You can modify this idea a little if you want.
You can attack people in your clan for fun, just like multiplayer. When you view your clan there will be an icon that will says "FIGHT" when you click on it it goes to a new screen that shows your base(you can choose weather it's your war base or regular base). You train troops and spells at your base. To make them it is instant and it costs half its price that you would have got it for. To train a level 4 barbarian it would only cost 40 elixir instead of 80 elixir. Then you can choose to fight anyone in your clan for free and no one will lose or gain trophies. And no one would lose or gain loot. It will just say the percentage.
I know now you might think 'No one will want to spend elixir when they won't get anything back for it.' You can just try it for a week and then if no one likes it then you can remove it. But please consider this idea. Thanks
