I get a lot of shit from league when I play Shaco and don't throw everybody on my shoulders and carry hard. Even if I go even or above average it's still my fault that we lose. Then I go ahead and play an Elise or Vi jungle and go something completely terrible like 1/5/2 and nobody says a word, yet if I go 4/2/4 on Shaco the only reason why we lost was because "shaco is a terrible jungler"
So many players in league are 100% pro followers and if it isn't one of the """top 3""" champions in that position they will bitch you out.
I've found out the best thing to do is suck mad dick, compliment your teammates constantly to keep their spirits up. I have no clue how many times I'll be supporting, my ADC blows ass, he's 0/5/0, then I make a huge play, flash + lantern + pull, into flay and box, with an exhaust and I do like 95% of the damage then the ADC gets the kill, and I'm all like, fk yeah, gj ADC. You owned that guy. Then all of a sudden, their dick grows 3 feet and they get all confident and start playing a thousand times better.
Nobody is ever going to play better if you tell them they suck. "You died, gg you suck" "gg gj wasting RP on a skin looool" So annoying.
