Practice Online Mode!

Hi Super Cell I love the game. It is perfect in every way possible. But I have a idea! You should make a practice online mode where you make troops instantly and it doesn't cost anything and you can attack bases online. You can test new attack strategies and the thing is you don't recieve any resources, not even a league bonus. YOU GET ABSOLUTELY NOTHING IN RETURN, except the knowledge of how troops work and such. Thank you for your time and keep up the good work!!

Step 1: Learn how to 3 Star your War Opponent.
Step 2: Know how to 3 Star your War Opponent.
Step 3: 3 Star your War Opponent.

It basically gives the ability for anybody to 3 star their war opponent.
This would be gamebreaking. Sorry, but I don't like this idea.
