[2023] Matchmaking to stop win or loss streaks?

I can assure you that the Random Battles matchmaking has no regard whatsoever for player skill, win streaks, or loss streaks. The primary concern of the matchmaker is getting players into matches quickly; something like what you are describing would be a huge burden on that.

Let me give you my favorite patent; a way for you to walk your pet snake on a leash :D https://patents.google.com/patent/US6490999B1/en

As far as I'm aware, no one is actually making snake collars as a product. Does the matchmaking patent exist? Yes. Are we using it for WoWs? No.
