No one is arguing the bolded parts. Classic strawman argument.
This is all I'm talking about:
You: A player at platinum is not somehow "better" than a bronze or un-ranked player just by the virtue of them sitting in the top ranks. They could be, but it's just as likely that they suck and simply had good luck with party compositions or had far more time to play.
Me: It is intellectually dishonest to assume that the Platinum player is not objectively better than the Bronze player, that winning is somehow determined equally by luck and skill.
