Matchmaking can't be rigged, loljk
4/5 games today I have a lane(s) where someone dies 3 times before level 6, then rages, then keeps on feeding out of frustration due to being called out for it by other teammates, just to prove how much they can harm the team if others don't stop hurting their feelings.
Add in a game where I had to dodge because someone was going to troll because his Katarina got banned.
Totally a coincidence that I just got promoted and was right after a winning streak.
It's not like all of them statistically have higher average death count than usual. It's not like all of them are ought to have bad standing due to reports. It's not like all of them have bad win ratios due to their total behaviour.
They will just all be on your team, over and over again, until the match system is satisfied and you get to go back to having the great teammates that I've had the pleasure of playing with.
I'm trying really hard to not think that there is something fishy, but as right now I'm heading towards a game where I'll be having a support Lee Sin for a nice 5th lose due to someone actively working against my team's interests, my doubts are all but evaporating.
