Counterpoint, people love Overwatch, they hate what Blizzard did to it. There's an audience out there hungry for this exact product if someone can do it right (or, at least, about 20% less wrong than Blizzard).
And yet they won't do it right because everyone wants to make a game as a service these days and sell loot boxes and collectibles with season passes, special editions, early adopter bonuses, login bonuses and in-game currency. If it lacks even two the things I mentioned, I'd be surprised.
Oh, sure, there's basically zero chance that this will actually be good. But that wasn't my point. All I'm saying is that the idea of releasing an Overwatch style hero shooter right now isn't inherently stupid.
