It appears World of Warcraft will be celebrating Diablo 4's launch with a themed event including XP and reputation buffs, a battle pet, and treasure goblins.
MMO Champion (thanks, Icy Veins) reports datamined details on the apparent crossover event from World of Warcraft: Dragonflight's latest PTR build. Its contents aren't testable at the moment, but the descriptions make it pretty clear that something Diablo 4-related is coming in the near future. Keep in mind that the event has yet to be officially announced, so none of this is confirmed, but the details are vaguely reminiscent of the Diablo 20th-anniversary event from 2017.
