The hate, and the bile. This is why I don't play ranked. But this year I'm giving it a shot. Why not, Right? I know I'm not great but the placement games where your thrown in with players that are 2 or 3 ranks higher than you every game. Then to have them cuss you, call you trash, and just berate you, as if that will help you play better. I've played so many other games and never seen as much hate as in this one. It is just a game.
It is also a competitive multiplayer game. In this case, there are expectations that the other players set for you and when you fail to meet them, well... That happens. Riot has given you plenty of tools to better yourself before you go in and waste everyone else's time with shoddy mechanics and poor decision making. Suck it up and realize that it is part of the game - just like at a job, where you are expected to meet a minimum set of requirements on the daily. If you fail to meet those expectations, there will be consequences.
Live. And. Learn.
