Interview by ML7 with alec dawson and gavin winter’s discussing upcoming balance changes
Everyone who played at the time knows and remembers this, but let’s put this into context.
It was a bug, it was only really a thing for a few seasons, and it was not all Mercy players only ones that had oddly low heal stats but were still winning games.
It wasn’t a problem at all anymore after Season 8 when they removed performance based SR for all games above Diamond.
Couldn't have said it better myself, other than to just clarify this was OW1 only problem and was fixed years ago.
