Rod Fergusson, the general manager of Diablo, acknowledged the backlash over the excessive grind in Diablo 4's first post-launch season, inspired by Diablo 2. Players were frustrated with the lengthy chase for Unique and Uber items. Blizzard's decision to shift from Diablo 3's instant gratification to a more traditional Diablo 2 experience was met with mixed reactions. However, the introduction of Season 4 and Uber currency in subsequent updates addressed player feedback and improved fan satisfaction. Fergusson attributed these changes to the evolving player mentality in the era of live service games, where time is more valuable than ever. The success of Diablo Immortal also empowered the development team to explore new class options, like the Spiritborn, moving away from classic archetypes. Blizzard's responsiveness to player feedback underscores their commitment to evolving and adapting Diablo for modern audiences.
