One reason why league players are the worst
Lets say you are at top and wreck your lane, get a few kills, get first turret blood....meanwhile your 4 teammates feed the shit out of a Fizz or something,and you end up dying a lot trying to deal with it...and then they use your score against you as if it was your fault. As if there was a different outcome when the mid is 2 levels and 7 kills ahead of you, and your teammates are useless.
League players are not just toxic. They are literally stupid people for the most part. Stupid people make people like me toxic. Its an endless vicious cycle rooted in human nature that is only exasperated by your personal rank being out of control in some many matches (feeling powerless leads to feelings of anger or sadness).
I really wish Riot would figure out a way to take the sting off a little from losing a match where you played very well and your teammates did not.
