i can confidently say that games below gold are decided upon random
hear me out; ranked games (solo and duo) are decided on the randoms. in the current meta, most games are snowball, towers go down quickly,etc.
one bad player and it really shakes things up depending on the role.
it seems like most of my ranked games go pretty well, and after 150 ranked games in season 6 I've decided that one feeder (usually the random) always ruins it for me.
there's no coming back even if all lanes but one are fed on your team, they can just grab free kills from your feeding teammate.
this might be a qq thread with no possible way to fix it but damn I really miss s5
tl;dr s6 snowball meta- one person feeds other team wins
