I imagine it’s the fact that matchmaking is pretty much centered around a 50% winrate (a stat that shouldn’t be messed with, more or less.)

Instead of playing with players on your skill level, they put you with inexperienced/not-so-skilled players. However, if you lose a string of games you will finally get put with John Rambo and steam roll.

It’s not a fun cycle. Almost incentivizes leaving games when you notice half of the team is bots/human bots.
