It's not ELO hell, it's just terrible people are in every part of society and also in League.
Just so you guys know that no ELO is safe: Diamond 4, a player immediately begins by accusing another of having a purchased account. As soon as last pick says he's not good at top, D4 player instantly goes off and mocks him for not being able to play all 5 lanes. Constantly throughout the game, he assumes that he is allowed to criticize everyone for things they didn't do because "Riot won't ban him for it." He defends his actions through his "Superior stats" and demands everyone bow down to him because he plays better than everyone else and his "Superior stats" support this theory ... The picture below shows truly, truly, truly "Superior stats." Without a doubt, his mocking of other players and behavior had nothing to do with this presentation of "Superior stats" and he wouldn't shut up about superior stats so I present to you his "Superior stats"
Note: The player's name is edited, but I just want to make a point of how stats don't mean anything.
