Surrender votes.
Context. My top lane Xin Zhao vs Teemo are both sharing info to each other about where the junglers are, which should guarantee at least a 14 day ban. My bot lane is Karthus - Thresh and are 2/8/4 and 1/8/4 respectively. My mid laner is a 3/3/1 Jax. I'm Eve, I am basically playing alone and am 11/1/2. Surrender vote comes up, I press no, everyone else presses yes. I was quite confident I could have carried this game regardless of my teammates, but I lost since they all pressed yes.
And what I'm proposing is that the strongest person on the team should have more of a vote on surrendering or not. I've been dealing with inting teammates for a long time, as is most of the playerbase, but a lot of players are still willing to play and try to win in spite of them.
What I can't accept is losing through some surrender vote, just because the rest of the premade players (top - mid, and bot lane were premades) decided they didn't enjoy the game and just surrender voted it.
P.S.: I'm not expecting any punishment for the Xin or the Teemo. That's Riot and the League community for you.
