I support the return of leagues. I think we should do away with leaderboards other than champion. I don't think there should be an option to stay in a given league. If you are good enough to make it to the next league, you should play there. If you get beat, your rating will go down and you'll be back in the league you are comfortable in, if this bothers you, then upgrade your deck until you can compete in a higher league. Also, I like the idea of having leagues in modern only. Wild is and should be a free for all.
