Solo Queue: Play Game -> Next Game->Same Group... rinse wash repeat.

Matchmaking be like: So, we got these two new players who are still in bronze... they're going to be your teammates in this high ranked gold match, that's basically a diamond lobby because we got a bunch of plats to diamond players on the enemy teams... but don't worry.... you get to babysit!

those two bronze: *dies*
you: *dies*

the matchmaking the next match: did I stutter? I said you get to babysit.

I had gotten the same teammates 5 matches in a row before, and no matter how many times I've reported them (because I had chat unmuted one of those times to try and work as an actual team since I kept getting them as teammates, and they were just cussing and screaming at me), the game kept giving me the same teammates. So, the game was - on purpose - giving me teammates who I not only lost a lot with, but had reported several times.

To those who think "SBMM" is a thing or those who think the matchmaking isn't rigged, here's your sign.
