A Price Barrier for Ranked

Ok so...after 5 games in a row of extremely toxic and rude players, I came to a conclusion: There are not severe enough repercussion for being reported or banned. Think about it. A player in bronze (home of the troll and feeders) get banned...so what? They didnt work to get to bronze. They didnt do anything special to get to bronze except spend a week or 2 getting to lvl 30. Then they are right back in bronze, making life miserable for players who really want to get better. There is a simple solution. If you want to play ranked, you have to buy a ranked pass. Nothing extreme, But i would pay $15 to play ranked for a whole year, AND riot could make exclusive content for people who do want to participate in ranked, like exclusive skins or something. EVERY OTHER GAME MODE WOULD REMAIN FREE for casual players. But this is the only game i play (besides dark souls), and I would very much enjoy, at the very least, a 50% reduction in the amount of trolls and feeders...just a thought. I have a feeling that, the people who really play the game, wouldn't mind $15 PER YEAR to have a more pleasant experience and some exclusive stuff.

What do you guys thing?

edit: ok so not such a good idea apparently...how do you reccomend RIOT fix the increasing amount of toxicity and trolling in the game? I dont care if someone flames me...its whatever and i can mute them. But i cannot mute someones gameplay if they decide to give up after 5 min because the enemy team got first blood.

edit 2: I have read from a few different sources, and hear from a few players, that this season is the worst season for feeders and toxic people ever. I almost convinced 2 of my friends to play, but after about 15 games, they uninstalled because they were constantly flamed and not helped but berrated
