The irony is that people complaining about their allies the most - and don't get me wrong, we all get paired with hopeless hands regularly, yesterday I had a 0 damage dealt PLD in my team, guess how it went - are often the players hard stuck in plat 4 trying to deflect their own shortcomings onto their team out of habit because they don't know any better, and can't control their salt levels. Removing the ratchet and I bet anything they all would drop back to silver/gold, if not lower.
There is definitely a factor at play with this system though, meaning that it prevents the rating to decant down significantly over time unless people get in high diamond or crystal.
