A summary for those who don't want to watch the video: Diablo 4 will have a rogue, Diablo 2 will be remastered and Diablo has a story.
Diablo 2 had a pretty cool story actually. I might be remembering things with rose-tinted glasses, but it's pretty decent and very nicely told. Especially the cinematics, since they're told from the perspective of a secondary character Marius.
Diablo 3, in comparison, just shit all over everything Diablo 2 had done before. I heard one of the devs, that was in charge of the story, say that it's nothing more than a lighthearted fantasy not to be taken too seriously. Well, the way they handled it in D3, no wonder it turned out like shit. Absolute shit. And I'll never forgive them for how they killed Deckard Cain. Those people obviously had no idea what they inherited from Diablo 2 and how to treat it with respect.
I'm convinced part of the reason D3's story and world turned out like shit was because of the way they handled the art style. They gave up on the gothic horror vibe, and just went for generic fantasy, like Warcraft, where you can pull shit like that. I hope Diablo 4, with its return to more horror themes, can ignore most of the shit D3 pulled, and just try and start over. And take it more seriously for gods sake. Diablo could be a very decent gothic horror story if handled with respect.
To be a bit more on-topic, here's the full b-roll footage they released for Diablo 4. I'm excited for the rogue. It jumped to the top of my character list.
