When it started, I thought it was fun, better than battling my dragons and keep losing. With mining, you just keep breeding and get bombs/ dynamites. The rewards are useful too: platinum dragons, expansions, fruits or coins. But now I have 2 Platinums, and about to get another one, which is way too many (i think!). Can I suggest that you create a system where we could trade dragons with friends, or trade our rare or super rare dragons with other ones which we don't have? That would be great!
