This legit is so annoying. I'm glad I'm not playing ranked yet. This is pretty unsolvable. Queue goes well, champ select goes well. Then loading the game goes to hell. Riot. It goes to a black screen then says "Unable to connect. Please check your internet connection..." For the love of God. FIX THIS. I JUST WANT TO PLAY YASUO
