Blizzard has released the first set of Diablo 4 release date is an excellent start.
"On the weekends of March 17 and 24, Sanctuary let out a cry for help," Blizzard begins in its latest blog post, which states that the team has "made a variety of fixes and updates to various systems in Diablo 4, all of which will be present in the version of the game that launches on June 6." These include some sweeping changes to make dungeons smoother, updates to the game UI and controls, and a number of balance changes to each of the Diablo 4 classes available at launch.
Diablo 4 dungeons will now see vastly more events, with spawn rates up to 60% from a meagre 10% previously, while backtracking has been dramatically reduced thanks to layout changes that reduce the need to explore side rooms to find core objectives. The agonising wait to place objectives on pedestals has been entirely removed, and you'll now get a full resource refresh and cooldown reset when doing so, allowing you to go into boss fights at full capacity.
Seeing the community's enthusiastic response to the most exciting (and terrifying) enemy in the beta, the Diablo 4 Butcher, Blizzard says the imposing figure will "present a greater challenge in world tiers three and four" than initially planned. Meanwhile, several of the bigger Diablo 4 bosses such as Vhenard, T'chort, and Malnok that were posing a dramatic difficulty spike for melee characters have had some fight mechanics altered to better balance things out.
Perhaps the biggest change in the notes is one of Blizzard's most subtle – players can now map the move and interact inputs to one button and put their primary attack on a secondary button. This was one of the most common gripes among ARPG veterans such as myself, who often favour a 'force move' option that ignores all enemies and simply handles movement and interactions, making it much more straightforward to navigate through crowds of enemies safely.
Balance-wise, all five classes see some changes. Barbarians get a flat ive damage reduction to help survivability. Druids have had numerous buffs to help mitigate their somewhat underwhelming early-game. Rogue changes make the class a little less all-in on its imbuement skills. The top two classes in the beta, meanwhile, both see some slight nerfs to some of their most potent tools.
Necromancer's minions won't last as long, meaning you'll need to use more corpses to keep your army's numbers up, and the devastating Corpse Explosion skill has seen its damage reduced. There's also a slight toning down of the visually overwhelming glow effect on summons. The Sorcerer's Chain Lightning also gets whacked with the nerf hammer, although there's no mention of changes to the Hydras yet.
One of the most common queries around the patch notes was a change saying, "The Reset Dungeon has been disabled." Blizzard has since clarified that this is intended to compel players to explore a range of activities rather than doing one thing over and over, although it notes that "it can be fun to repeat a specific dungeon and the team is looking at a more permanent solution to this, like having some reasonable cap on how many times the same dungeon can be completed in a row."
It adds that another consideration was "that resetting the dungeon wasn't a way for Hardcore players to avoid death when experiencing a challenge." There's good news for those players, however – characters will now be immune and untargetable after loading into an area, so you should no longer run into situations where you could potentially be killed immediately upon loading into an area before you had a chance to respond.
All in all, the changes are extremely encouraging to see – not only has Blizzard addressed most of the community concerns in smart ways, but it has also communicated its thoughts and future plans clearly to players. Initial responses to the $15k Diablo Immortal gem fiasco – simply proclaims, "They are listening."
