Mercy will be balanced claims: I’ve heard people say that people are still learning how to play post nerf Mercy, and that the numbers will get better once people figure out what maps/comps she’s good at. From the start, this claim is dubious. Mercy has been around since the game came out and, she’s not hard to figure out. Mercy should be good on maps with lots of verticality, and should be good in mobile comps that can exploit vericality, as well as comps centered on long range damage. I don’t think higher ranks players have any trouble at all figuring this out.
Looking at the data however, this claim doesn’t appear to be true. It’s been a month and the win rates show no indication of an upward trend. Mercy’s pick rates have already plummeted quite severely. People have already heavily restricted the situations they play Mercy in. They just haven’t found success. If this claim were true, you would have expected to see an upward trend when the pick rates decreased, especially in higher ranks where people make better strategic choices. It’s just not there. As a side note: the hero you are thinking of when you make this claim is Zenyatta. His pick rates have gone down, but his win rates have not.
In order to believe this claim, you need to believe an very unlikely constellation of ideas. This claim has grown a beard and needs a shave from Ockham’s razor. Its fig leaf of plausibility is shrinking by the day and it’s becoming indecent.
