People are so shallow in this game, its embarassing
A person can be the most toxic, insulting player in the game with a horrible attitude and horrible ego but if they happen to do well (because people like that usually pick the overpowered champs to compensate for their lack of ability and call that "skill") then people end up honouring them. It really is disgusting to watch and completely destroys my faith in the human race.
Ego and Arrogance are BAD traits in people and should not be rewarded. It is so self-serving of other people to honour these circle-jerkers just because they carried a game, or won a game. That doesn't make them decent players and with League's current formula, it becomes increasingly based on getting a lucky first kill and then snowballing so far nobody can catch you. Its not difficult.
