When its generally released I'm hoping they have a few tournaments on offer and you could select the one you want to do. Each having different rewards and requirements .... like the quest feature. Also if you fail the first time you get more chances to do that particular tournament until you get the dragon reward.
That way the people who don't have the yin yang have a chance to get it and those of us who have already gotten the yin yang can go for a different reward.
I got robbed. They didn't give me the dragon. I'm disputing it via email.
Has anyone noticed that the tournaments battle is going up in price.
