Can we make picking meme champs in lane a bannable offense?

Is personal MMR a thing in that we don't have to win games to get a boost in MMR, but just do good personally? Getting sick of getting matched with people who wanna play Soraka jungle, Lee sin support, Teemo jg, Kha'zix top etc. I want to have non meme games where people actually try to do well. These people feed, throw the game and I lose a good chunk of LP because of it. I do well personally as my stats will confirm, I feel I belong in a higher elo but can't push past because someone is always feeding like a MF. How do you guys break through gold (I know this is trivial for some people but it's clearly not for me, do you just get lucky and not get trolled by your own team)
