Now I understand why

I don't really get it, but almost everytime I try to play a ranked in Silver 1, I actually can't leave this division, everytime I play, I get someone testing a champion, flaming all the teammates, running it down mid, just because that person got autofilled they troll, sometimes I do the mistakes. Now I get it why leaving Silver is so hard, it's not always about you, it's about your team so if someone of your team decides to troll or fucks up, there's literally nothing you can do, than accept defeat and stay there. I don't get it. I just dodged a game where I had a support troll because he got autofilled, I am at 30LP I had 99Lp, what even is this??
