Many fans would say that the endgame in Diablo 4 is good on paper, but it needs a bit more to Diablo 4 Items offer in terms of pure content. A quicker respawn on World Bosses, better Nightmare Dungeon layouts, and repeatable Strongholds have been some of the game's most requested features. Though it remains to be seen if and when Blizzard decides to expand on Diablo 4's endgame content structure, the willingness of the developers to increase rewards in Nightmare Dungeons and Helltides implies that they're more than willing to listen to the community.
The suggestion, submitted by TheCruelHand on the Diablo 4 subreddit, is simple: instead of being permanent, Strongholds in Diablo 4 could be subjected to a weekly reset. In addition to becoming repeatable, Strongholds would change their modifiers similarly to how Nightmare Dungeons have different affixes, and even the bosses could be fully randomized. Given that it doesn't take long to clear a Stronghold, it wouldn't hamper Diablo 4 players too much in restoring every Stronghold's waypoint.
Another genius idea for Diablo 4's Strongholds came from Kyriolex in the same thread, where they suggested that players could also (optionally) tackle Nightmare Strongholds by activating Nightmare Mode through Stronghold Sigils. Though some fans are worried that the novelty would wear off quick, having the ability to break up the current monotony at endgame would be appreciated. The grind to obtain a perfect set for gear for any Diablo 4 class is far longer than it used to be in Diablo 3, and having to run the same content over and over again is hardly anyone's idea of fun.
On the flip side, turning Strongholds into a weekly grind might backfire, as it could easily introduce a bothersome grind for players to deal with every Thursday. Perhaps the best solution instead would be to place the reset button into the players' own hands. Ultimately, Season of the Malignant in Diablo 4 will introduce Malignant Tunnels to the game, and though they may not be the repeatable Strongholds that players have been asking for, they should still hopefully add new depth to Diablo 4's endgame.
Though Diablo 4 players who create Hardcore characters tend to be fully aware of the consequences, a new griefing method may cause them to unceremoniously end their playthrough in an unfair way. The Hardcore community has come a long way since Diablo 2, as it also found new battlegrounds in Azeroth, prompting the developers to add an official Hardcore mode to World of Warcraft. Accomplishments, achievements, and victories in Hardcore are valued tenfold, as players can lose entire weeks of progress in the blink of an eye.
Many Hardcore players have lost their characters to Uber Lilith in Diablo 4, and the appeal of the playstyle primarily lies in that rush of adrenaline – of knowing that one fatal mistake separates a D4 Gold completed Hardcore journey from having to start over. Though most in the community accept that a disconnect or some other factor beyond their control can (and will) end a Hardcore run, a significant amount believes that fairness needs to be preserved.
