I'm curious how credible the source of that article is. I keep rereading this leak, and I am 100% convinced it's fake.
First off, it very much reads like it was generated by ChatGPT and then edited. ChatGPT loves to form meaningless fluff sentences like this:
"Each location presents unique challenges and opportunities for the Spiritborn, whose connection with nature will be tested like never before."
Kurast Sewers being in Nahantu also doesn't make sense. Kurast is the former capital of Kehjistan which is an existing zone in the game. Nahantu doesn't exist in the current lore, and there's no way it can appear out of nowhere in the map of Sanctuary and be comparable in size to the 5 playable zones in Diablo IV. According to the leak, it would have to be ~5 times the size of Khejistan while being inside the borders of Khejistan. Also, does anyone really want to go back to Kurast Sewers?
I can't see there being a Khazra raid. They're minor villains in the franchise. They're not a major faction like Beastmen from Warhammer Fantasy. They would be an extremely odd choice as the antagonists for the game's first expansion.
Spiritborn seems to overlap heavily with Druid themes. I have no idea why they would add a class like this when there are major class archetypes/fan favorites like Paladin and Amazon still missing from the roster. There is definitely design overlap between the Rogue and Amazon, but there is nothing reminiscent of a Paladin in-game. The only class that currently uses shields is the Necromancer, and they just use them as a stat stick. Necromancers also currently hold the role of preserving balance in the Diablo universe.
Seems very questionable to me. Especially with how rough the past few months have been. I can't see this new class receiving an overwhelmingly positive reaction at Blizzcon. I could see a lot more excitement if a previous class or archetype was announced.
That is also an extremely long-winded class description that doesn't give that much tangible information on how the class actually plays. This is not how Blizzard or game designers generally write class descriptions. They're short and sweet and easily digestible so players can quickly compare classes at a glance and make a decision.
This is the Druid class description from the official site for comparison:
"The Druid is a savage shapeshifter, fluidly transforming between the forms of a towering bear or a vicious werewolf to fight alongside the creatures of the wild. He also commands the power of earth, wind, and storm, unleashing nature’s wrath to devastating effect."
Diablo IV classes are also not defined or restricted by specific weapon types in this sort of overt manner.
I don't see anything in this leak that is so exciting/mind-blowing that it would make folks who quickly abandoned the game after release give it a second chance, but that's just my subjective opinion. This just seems like more of the same to me.
