Smurfing
Literally, so many posts here are complaining about smurfs. I hope they realize there are no way to stop people from smurfing. Regular players can't do anything about it and I doubt Riot would do something about it either. If you get one and you get completely crushed, big deal it's a game, try again. And what's more, YOU LEARN FROM IT. Only the worst of the worst perfectly define Einstein's definition of insanity: doing the same thing over and over and expecting different results. Your best teacher is not your best teacher, they are your best helpers; your mistakes are your best teacher. LEARN FROM DEFEAT AND LEARN FROM YOUR MISTAKES PEOPLE, SIMPLE. Do that and you won't get crushed!
