Matchmaking's kinda broken
TLDR: I got placed with substantially worse players after losing 2 games.
When I first started this season I was Bronze 4 cuz I hadn't played for a long time and I was Bronze last season. But a week after i had been placed a started the long and hard climb and managed to drag myself up to Bronze 2. I thought it was all going pretty well however I got stuck at around 20-40 lp and lost 2 games in a row. Suddenly (not pointing fingers) I started getting placed with bad players. I understand my MMR had dropped quite a bit and I was pretty on tilt but some of these players were truly awful. They chose bad picks or played champions which they hadn't played before and before you knew it I was right back down to Bronze 4 with 50lp wondering if I'll ever get out of Bronze. I do understand I've been losing a lot causing my MMR to plummet and that I've gone 0/4/0 (mordekaiser) but I've also gone 21/10/3 ( akali) and 18/11/11 (gangplank) where I was doing really well and the only reason I lost was because of my teammates. That all aside what I really want to know is why I suddenly got placed with players far worse than the ones I was playing with just 2 games before.
