In order to provide more players with more flexibility, Blizzard has opted to do away with traditional raid class sets in World of Warcraft: Battle for Azeroth.
"We’re currently not planning on carrying forward traditional raid class sets," World of Warcraft game director Ion Hazzikostas said of the MMO’s recently revealed expansion in an interview with Game Informer at BlizzCon 2017.
In addition to noting that "gear will be more heavily themed from the place it comes," Hazzikostas said Blizzard has more customization it wants to feature through the game’s new Azerite system, which will feature options like enhancing abilities so players can tailor their gear around their specific strengths.
