"It's telling that the top voted comment on the Diablo 4 Reddit post(opens in new tab) about the customization video is someone spotting that you can skip the story campaign for your secondary characters. For a Diablo game, that's a vital feature that shapes how you'll interact with it over time, especially because it's the first truly live service entry in the series. This is the kind of information players have had to share with eachother by leaking endgame footage and breaking an NDA to talk about. Imagine if the developers themselves just said this kind of stuff on camera, and didn't leave these broader details hidden in a few frames of footage."
