Summoners Rift
Gold III last season before I had to quit for 7 months to focus on school, got demoted through LP decay to silver II I think, or III.
Made bronze I this season, thought "o.k, will give me a chance to experience what it is like in bronze if its really what people say it is. Since I've never placed in bronze.
Now, I find myself uninstalling the game because it is no longer fun. There is no teamwork. I've played games of solitaire that required more teamwork then what I've experienced in league this season.
