you should be insta banned for leaving ranked game on purpose
im not wasting my time in that game so im forced to afk too and waste 20 min because of one jackass? I dont think they deserve to play anymore if they treat it that way. Sure things happen but when you say "fuck this game" and dc after dying level 2 because you played it terrible is not a good reason to leave a ranked game or continue to be able to play ranked.
