The POINT I am making is a perfect matchmaker will throw all of the same things you complain about.
Sure, you have a smurf… now. What is the matchmaker to do about that?
No amount of saying “Ok, these are the things you have as tradeoffs in matchmaking, WHAT WOULD YOU CHANGE?”
And people people just bail the hell out of the conversation because they don’t like the tradeoffs is also frustrating.
What changes do you want done?.
Do you want them to matchmake closer in MMR and accept the time difference in getting matches and more patterns in win / loss streaks?
Do you want them to make the matchmaking loser and get more " where losing team has 3-5 total elims and winning team has literally 70+ " games?
Do you want them to move the MMR faster, and get people saying “it is forcing a 50/50 win rate” more?
Do you want them to move the MMR slower, and get people saying “it has winner /loser queues more?”
WHAT CHANGE DO YOU WANT? Specifics. How do you want the tuning to change?
You have width (people getting picked from further away MMRs or only from closer ones)
You have speed of MMR shift (one side gives people complaining about 50% forced rates, and the other gives people complaining about streaks)
Which direction do you want these things to be moved?
