He will probably go live close to as is. I don't think he will be completely different from current numbers just because of the shit we know from someone like Ana or Sombra.
They're firm on the idea that all is illusion for now, and that they'll roll him out into the real world. Everyone thought sombra was going to be op broken, but it took awhile for her to catch on. Ana was thought to be shit, but ended up being the goto meta pick.. She did have a small adjustment but that was only to her nade splash.
From the looks, he will probably be relatively easy to shut down. Even watching seagull play, he's gonna be one of those Hanzo/widow characters where the people who are good at him, are good... And the people who aren't, you question why they're playing the the game.
I could be wrong but idk, I think he's hype strong.. I'm putting on money when he goes live within a month or two he will probably see some adjustments to make him better.
