Broken Ranking System

This is the ranked game I just came out of where, in the beginning, I won my lane. Meanwhile my entire team doesn't understand you can lose lane without feeding the shit out of your laner. I am so tired of this same bullshit. Win lane; lose game because of fuck-up teammates. This is me being toxic as fuck, and it is warranted. The Elo system was designed for chess, an individual game where you are in complete control how the game goes. Meanwhile you have four randoms who don't know what they're doing, feeding, or trolling. Things like this is keeping me from climbing back to my place in silver 4. I don't deserve bronze five.
