Why do Some Argue Against Skill Based MM?

DeviouslyCursed: Hall of Fame is easy to get into now. It goes month to month, anyone can get lucky and place in it. For instance, I'm currently in the top 100 players for win rate right now. Sitting at 92nd place. I'm at 82nd place if you use the tier 8-10 option. If the Chinese 122 had a spot (for some reason that tank isn't listed), I'd be in the top 10 for it easy, with a 71.88% win rate for the month. SimplySimple's actual account is over 2000th place in overall win rate. And he disappears when you sort for tiers 8-10, because, well, you know.
