I got this from Eventhubs, which in turn got it from Cat Cammy on Twitter/X.
I'm really glad someone has compiled this data, and that it shows the game is really well balanced. Very few match ups above 6-4.
On the other hand, I'm disappointed that the two characters I play in earnest are both below 50% win rates. Also, I'm not Master ranked so it doesn't really reflect what its like at lower ranks.
So the data is neat, but won't impact me personally much. I'm going to keep playing my scrub Marissa and Honda. They're fine at my level and suit my playstyle just fine.
I feel like this data has survivorship bias. But interesting none the less.
