It's a very fun and addictive game. But there are a few problems. The biggest problem is the ranked system. I'm only a rank 17 silver yet I'm literally going against level 28 golds and even a level 43 at one point. It makes it difficult to win and earn diamonds. Also with the random battles you can find a special battle with a different concept. I wish that there was a seperate way to get to these a lot easier instead of by chance on random battles.
