It's very optimistic. Even under new leadership the creative talent that Blizzard has lost over the last 10 years is not coming back. Microsoft themselves aren't particularly good at picking talent either - see the Halo Infinite/343 Studios debacle. Maybe there would be less of a push for player-hostile monetization, but I wouldn't count on it. The people who made and executed those decisions at Activision/Blizzard aren't magically going away either.
