I’d love for Blizzard to pursue a genuine passion project. Ask the Microsoft overlords for a few years to put out something not beholden to sales expectations or profit. They can devote a small team to make something that they want to while the rest of the company continues on with its soulless corporate entertainment fabricator to fund the creative projects. You need creative projects to keep the workforce engaged.
If nothing else, Activision Blizzard was seen as a greedy, profit-driven machine which continually pushed out semi-entertaining products with en emphasis on FOMO micro-transactions and monetization schemes. Blizzard is a shell of what it once was.
Let them get back to their roots. Let them focus on engagement and fun.
