Diablo 4 will essentially be a whole new game when the Vessel of Hatred expansion drops in October, with Blizzard completely overhauling the difficulty systems by removing World Tiers and redefining difficulty stages.
During the Diablo campfire chat on Aug. 29, the developers discussed upcoming changes to Diablo, especially the various endgame systems, tiers, and how they correlate before eventually dropping off and becoming irrelevant. To counter this dropoff, the devs have decided to remove World Tiers when Vessel of Hatred goes live, with The Pit now set to become players’ difficulty guide and the “backbone” of Diablo 4.
