I'm done with this ranking system

Dear fellow summoners,

My name is MadCurmudgeon13... Hi! I recently hit level 30 and decided it was finally my time that I can play ranked. I duoed with my friend that i think was a perfect partner to get me into a rank. Sadly, I ended up in bronze 3. XD! After that occurrence, I ended up going on a 15 game lose streak, and guess what? I'm Bronze 5 now! YAY! Eventually, I ended my tilt by playing some normals and i started to win some games again. When I motivated myself that I can do it and climb the ladder, I was vastly disappointed by the gameplay i experienced for there were many troll picks. Now i wasn't going to afk, dodge, etc. for these people, but I finally reached the point I should say something. Rank people on their skill, not saying that I'm good, but just do it. Lets say i went 22/7/10 by the end of the game, and because of a team comp that consists of 4 other supports, we lost. Recently, i mentioned my great demotion 15 loss streak. Within those games, sure i did bad because i was tilted, but they weren't feeder scores. I was playing as safe as my brain would let me, and when i saw opportunities, I took them. Now I understand that this just looks like some butthurt bronze player with no skill, but c'mon, I'm just speaking for the people that want to climb. And it's very hard to do that when you have 2 supports playing bot, because they refuse to accept the fact that "bot" is the same as "adc" and they won't leash you because they decide to roam into the enemy jungle at level 1. I can't deal with a blitz top that took smite, A soraka mid without flash, and an ali/jhin combo that fed 0/22 in total. I'm sorry, I love the game, but this ranking system, its just too much.
