About the tournament quest I see really a big problem. Look for today: Their was one tournament 19 hours ago, than one goldfoil tournament where most players cannot participate and than 5 hours ago the next regular tournament. So you go out in a tournament and have to wait 14 hours for the next tournament ?

Or take another point: From now on their are only gold / diamond tournaments in the next 24 hours, what if you take the quest in gold league but fall down back to silver league - you should than pay DEC that you can participate in tournament and you need this participation to solve your daily quest
