Anyone able to explain this QP Matchmaking?

Can anyone explain to me how the QP matchmaking is supposed to work? Yes I recognize that QP is different from Comp and it’s a bit looser with how it pairs players but this is ridiculous. My winrate on support is currently 53%, G3 in comp, and over a hundred QP games this season so I cannot imagine this is the lobby I should be in. Or near. Or around.

Any visible profiles are shown. Missing DPS went 9K 7D and I cannot recall how much damage. I’m not sure if there’s a way to force a replay to use scrambled usernames so I won’t be linking it.

I believe that QP and comp have separate MMRs

I’m convinced that it’s so loose it might as well have no range. I’ve had bronzes and masters in my games literally at the same time. It’s gross.

First, stats aren’t enough to tell if the matchmaking has failed or not. Especially in QP, people can try some other heroes or just play less intensely.

2nd, QP has leavers and backfilling. It is not known how backfilling is handled by the matchmaking : does it go for the fastest or the most balanced backfilling player ?

3rd, QP and Comp MMR are separate. You can theorically be GM in QP but not in comp.

Devs have told over and over how their matchmaking system works. Some variables aren’t precisely known like predictability ; but they’ve shown they reduced the rating span between players.

I appreciate the info; unfortunately all I can find on the subject were old posts, generic ‘we’ve adjusted the matchmaking’ patchnotes and outdated websites. I posted a picture there with their comp ranks, hours played and some other info. No leavers that match and thus no backfilling. I could see how a few of them haven’t played QP in a while and perhaps there’s some hidden MMR decay in place, but all of them? At the same time? And if they’re a full premade team then why am I getting put against them as solo-Q? Even if the rest of my team was a partial-premade, then why fill a GOLD 3 support against that?

Comp and QuickPlay has the same matchmaking system. Only difference is that comp has a tighter spectrum than quickplay when creating teams. If building two team is too difficult, it will loosen the MMR when searching for players.

While both Comp and Quickplay uses the same matchmaking system, they do not share the same MMR.

In Quickplay, if someone leaves your game, the matchmaker will try to find another player to fill the spot. This is not guarantee, as I have experience games where the enemy team did not get a 5th member the whole game. In Comp, if someone leaves your game, your team is screw since there will be no backfill.

The match maker will make the team on both side have each coorespending role have the same SR or MMR. For example, if your team has a gold tank, the enemy has a gold tank. If your team has 2 silver dps, the enemy team will have 2 silver dps. If you have a plat support and a gold support, the enemy will have the same plat and gold support. Quickplay backfill however, breaks this logic.

Do know when someone leaves your quickplay games, the backfill player will often be a player of higher MMR, thus they can sometime turn the game around. Heck, I’ve experience games where the backfill steamroll the game. I’ve had games where the whole enemy team left the game, only to have even higher skill players fill the whole enemy team for the 2nd map of the match.

I pretty much only play QP, since the first beta of OW1, and I’ve never really felt like there was any real matchmaker in it. As a solo-queue support player I’ve seen every level of player mashed together in it, from GMs to bronze. But it’s kind of why I dig it (on it’s good days), because you never know what you’re going to get.

In OW2 I’ve noticed that whenever the Devs talk about matchmaking and the troubles they are seeing, they only really ever talk about how they are going to adjust it for Comp. They never clearly state that they are going to do anything with it in QP. So I suspect that it will always be a mode where they just throw the first warm bodies at it who are available in that moment.

I’ve been put in QP matches where I don’t even get to pick a character, the literal moment I’m put in the game I just see the word “defeat” pop up on the screen.

That’s how seriously Blizzard takes QP.

I can tell you right now regardless of the queue’d matchmaking, I believe it cares very little for the stats of the backfiller. I’ve backfilled and absolutely dominated a previously-losing match for the team.

I suggest the reading of the playoverwatch blog articles ; there are 2 or 3 articles about it since December 2022.

Comp Rank isn’t a good info to assume MMR since even devs told there aren’t equal. Even my Rank lately switched for a whole division as my winrate went from 52% to 51% in 30 matches…

There is a MMR decay if the players don’t play for a certain amount of time, even in QP. Its not known what is that amount, I think its something beyond one week based on my experience but no hard evidence of it.

What’s interesting about the profiles you posted, if there has been no backfilling, is that there’s a 30hrs account with only 14hrs in QP. So its likely the MMR is wrong for that account. MMR needs a lot of games to fit one’s skill level.

Also we could speculate about the stats from the leaderboards. Enemy Ana had a bad game compared to her mates. Your Ram seems to be the best of your team and we’re missing one DPS stats. So, if Ram and the msising dps are beyond gold, the match was actually balanced : 2 Golds + 3 above Golds in each team. Its fully assumption ofc.

Bottom line is, its almost impossible to know how bad the matchmaking is just based on skill ratings and leaderboards.

About matching golds against Plat/Diamond is probably due to the “predictability”. I guess the matchmaking wanna challenge some players by matching them with lower/high ranks. The span of those ranks is kinda debatable though as it would make some games feel “impossible to win/lose”.
