the odds of a high elo game NOT being one sided is unlikely.
its nearly impossible to try to win games where u are behind.
if i for example go 5-1 on lee jungle with every lane pressured, and lose because i have a 1-9 adc and 1-8 top who said "im going to run it down mid". i cant actually try to win that
if you queue up expecting for a fair game, you arent going to get one. the odds of who has the moron with the "bad game" or the "800 pign" will either be on your team or theirs. thats how you win. its not skill or mechanics. me killing 2 of them level 5 didnt stop my vayne from suiciding over and over to a morg supp.
me ganking my mid didnt stop her from diving a fuckign sion and gragas and dying over andover.
it certainly didnt stop my top from pushing up behind enemy turret level 6 and then whining about a 3 man gank.
why try anymore? who GIVES a fuck about being good? why bother when you can just stall out 600 games and get master tier?
3 games before that i had an intent feeding jungle yi who went 1-12 with no ganks. the game after that i had another yi main run down mid saying he didnt care about the game.
whats your point riot?
