When you play in League of Legends ranked mode, you get placed in one of I expect many leagues.
For instance here I am in Poppy's Avengers.
Do this league change anything? Does being in Poppy's Avengers change anything to the game compared to being in another league?
Also, bonus points if there's a list somewhere of all these league names. I'm curious what characters have a league named after them, and who doesn't.
