Please Fix Matchmaking

It's just disgusting who I get put up against, and I'm pretty sure at this point Riot is genuinely forcing everybody to have an exactly 50% win rate.

One game, I get paired with Bronze players, the next, I'm up against a fucking Diamond player and his Platinum friends. I play at a mid Gold level, yet I rarely, if ever, get put up against so much as a Silver player.

Yes, I'm aware that matchmaking is supposed to "even out" as you level up, but this isn't my only account, I have another that's level 67, and it faces the same fucking issue.

Not to mention with matchmakign being as horrendous as it is now, the moment I get so much as a 4 game win streak, the system automatically starts pairing me up against fucking Diamond players, which forces me to go down, on average, anywhere from an 8 to 12 game loss streak before it "evens out" again. The longest streak so far was 17 games, 17 FUCKING GAMES, and it was because I was paired up against players way the hell above my elo. I got out LoLSumo, I got out LoLKing, and looked these players up, and in every game, I was paired against anywhere from Platinum 1, to Diamond 1 players, and in 1 of those games I actually faced a Challenger player. I was Gold 4 on that account, why the fuck am I being matched with Diamond players?

I swear to god, if Riot doesn't fix their matchmaking by upcoming preseason, I will genuinely, truly, quit this game. I've been playing for 5 years, and this is the worst season I have experienced.
