Whats your total win rate?

Please review this. It’s a detail explanation of how the system works. he provides links from developers and what not as well.

this is a very detailed explanation!

Pay particular attention to sub-section “matchmaking”

@Kaawumba-1133

If the match-maker says most games are fair, then why are there so many stomps?

There are many reasons:

1. Overwatch, as a game, has a tendency to snowball. The winner of the first fight has an ultimate advantage that has a tendency to last the round. Losing teams tend to tilt and start playing poorly, which can continue in the same round and carry into the next round.

2. Random variables are random. Maybe a cat walked on a keyboard or someone fat fingered an ult (7). Maybe someone who has 99% up-time for their internet had their 1% failure that day. Maybe one team has all dps mains, and the other team is well balanced. MMR and predicted win percentage only has validity over many matches, not each individual match.

3. Not every player tries hard every match. Sometimes this is subtle, like playing with a beer or two too many. Sometimes it is less subtle, like practicing a hero a player is not good at, regardless of team comp or map.

4. Some players actively break the system, by either hard throwing, that is intentionally losing (as opposed to soft throwing as in item 3), playing on someone else’s account to boost it, or other similar actions. These actions are bannable and should be reported when seen. Blizzard has promised to take stronger actions against this sort of thing (17). However, soft throwers and hard throwers can be difficult to distinguish, and Blizzard has to error on the side of caution to avoid banning the wrong people, so it will always be a problem. The in-game report UI, as well as a key blue post (36), give guidelines on what behavior is or is not bannable.

5. New accounts in general have less data and will have a less accurate MMR. There is no required minimum number of games to play, so new accounts can stay “new” for a very long time.

6. MMR itself is only approximate. See the section on “How Accurate is SR”, below and realize that MMR generally will have the same issues as SR, with respect to accuracy, except it is harder to measure what is going on with MMR.

Okay, stomps are going to happen, but why are there so many win/loss streaks and large SR/MMR movements? Shouldn’t a player’s SR/MMR be fairly stable once he gets to the proper rank?

Win probability changes slowly with rank because there are so many random factors in each individual match. Unfortunately, it follows from this that frequent and long streaks will occur, and a player’s rank will oscillate widely. Essentially, a player will tend to bounce between the range of where he is nearly guaranteed to win and where he is nearly guaranteed to lose. The range varies from player to player, but +/- 250 SR/MMR is common and +/- 500 is possible. This problem can be analyzed in depth, mathematically (34).
