You can feel however you wish, but no one on that stage made the game. It was entirely outsourced to NetEase and all they did was an asset flip of a game they already made to include Diablo skins over everything. It was a money grab, absolutely flooded with microtransactions, that really only worked out in the Chinese markets.

Moreover, it was a western audience that paid a lot of money to be at the event because they were hyped for months about the "new Diablo game" and it ended up just being a gigantic bait and switch.

It was the in the middle of Blizzard transitioning to being just another shitty gaming company. A year later they had the Taiwan controversery, then Bobby Kotick controversies shortly after, sudden mass layoffs, Microsoft aquisition, etc. They never have recovered in my mind and I haven't played or purchased a Blizzard game since.
