Diablo 4's Vessel of Hatred continued a year-round effort from Blizzard to improve the base game beyond the addition of new expansion-exclusive content. Numerous changes were made to the gameplay loop and various other mechanics throughout the year following Diablo 4's launch, and Vessel of Hatred capitalized on all that with a plethora of big updates. From new active and passive skills for Diablo 4's classes to the party finder to help the game's MMO side, the expansion has made a big impact overall. One of the biggest changes was made to the game's difficulty options as well as the progression from early-game to high-end content.
