I only wanted some useful items in D3 vanilla.
I’m really holding out for an enormous Super Awesome Sparkle Cake boss.
Kind of my point. They’re integral to the story, so fights with them should be part of the story/campaign (at least when you first face them in their territory), not optional events that have no impact on the story.
There are only three Prime Evils Mephisto, Baal, and Diablo. The others are The Lesser Evils Andariel, Azmodan, Belial, and Duriel. Collectively they are The Great Evils.
It would be interesting if the first 7 world bosses are ex-D3 characters, like, one randomly generated from each of the classes so you get either a male or female barbarian, or similar for a crusader… etc. This way, the game retains parts of its history through inclusion but also allows for some interesting moments when a witch doctor firebats the Nine Hells out of you.
