Network asynchronizability makes the game ♥♥♥♥ed

[HoAhNam]

There are some reports stating that by interupting network connection during the first 30 seconds before actual battle, a player may easily try as many attacks as possible on a particular opponent before setting off a real battle without losing any troop or spell. By this way, he can earn almost 3 stars each battle. I don't know that this is a feature or a bug or the limit of the game. My clan was attacked by those taking advantage of this ♥♥♥♥♥. This "feature" completely kills our belief. There is no fun at all!

Yeah it is possible (clan tried it on us as well and they still failed). I think they are working on a way so people cannot do this.
