Performance can equal towards skills, stats? No.
A otp reaper solo ulting repeatedly when his entire team gets wiped and kill 3 foes on the point. Will lead the team to lose. Yet he could, based on stats, lose less than its peers.
In general winning more than losing should do the trick towards what rank folks should deserve. Although due mmr discrepancies in matches that can lead to advantageous or disavantageous matches, that can lead to more or less mmr changes based on your mmr towards the match value.
If the game was deathmatch based, would make sense. Due kills actually matters. On ow matches, kills aren’t that important. Although can be, normally, the easiest way to control the objective.
You can win without killing anyone by simply pushing a payload or taking the point while the other team is not looking. Which is what pretty much C9 is.
I would understand solo hero queue on a deathmatch having performance metric. But on a teambased game that leans on objectives, not kills. Would be irrelevant.
I understand why marvels adopt it, tho. Because also OW1 adopted their current mechannism in the past, by providing more gains in wins than losing on losses.
Marvel rivals paired with, usually, more gains than loses. This system can offset that problem on higher brackets.
On OW, due it’s age, there are some really defined mmr points already. Paired with the flawed RQ system. Performance metrics only actually happens if were open due that could gauge ability to the player to perform in a match based on the matchup and map.
Due:
Specific maps favors specific heroes, specific parts of map favors specific heroes, specific metrics like (deaths prevented, players saves, assists, objective time, how many health packs picked or hacked and so on) can provide some info on performance paired with the adaptability and performance on each part of the match. But again, not raw numbers or stats, but instead cross reference favored heroes for specific map portions, kinds of plays and so on.
Performance metrics is way more nuanced in a game with objectives, which is why on marvel makes sense due how their objectives works.
Overtime limits, auto move payloads and so on. The game tries to make folks care less about objectives and more about deathmatchs. Which is not exactly what OW aims for. Push, hybrid and control points requires effort to be on the point to win. Marvel just requires “conquest it” briefly.
Fun aspect? Well that can be solved by splitting the playerbase towards what they should be playing, instead of the clown fiesta of casuals and try hards on pretty much all modes due it’s similarities.
