Ranked Matchmaking

Matchmaking hasn't been fixed at all, still getting paired with trolls and people feeding on purpose. I will never get out of bronze everytime i have a promo it never fails i get paired with people who just go AFK or feed over and over again.

How the heck can you get paired with people that understand the game then get paired with people who just want to troll. Someone please help me understand how this riot matchmaking works. This type of crap just makes you want to uninstall the game and just go play some thing else. Spent like 300$ on this game and i'd rather just call it quits. Getting so frustrated and annoyed someone please explain to me how this new update fixed the matchmaking to make it more even???
