Blizzard has officially delayed the start time for Diablo 4 Season 2, Season of Blood, and so now it's unclear when the new season will actually start. Diablo 4 had a successful launch, breaking sales records for Blizzard and earning a great deal of critical acclaim in the process. Unfortunately, Diablo 4 was unable to keep that momentum going. Diablo 4 Season 1 was panned by the community, with many fans revolting against the changes Blizzard made to the game.
