and for things not covered there I’m always willing to talk about the matchmaker. I’ve done quite a bit of testing on Overwatch over the years from MM documentation, when the game didn’t have private profiles, to the punishment systems.
I encourage you to read as much as you can about it but please don’t take Cuthbert or Receipts seriously. Their fanatical devotion to “the matchmaker is holding you back” is ludicrous, at best.
