At this point in time, Blizzard has not officially commented on the missing names from the list. It's currently focused on revealing details about Diablo 4's upcoming first season, the Season of the Malignant, which launches July 20.
Diablo 4 is soon approaching its first season, with many new and Diablo 4 Gold dedicated players still exploring the depths of Sanctuary in the meantime. The new season and those afterward will inevitably introduce new content to Diablo 4, although what that entails remains to be seen. After the first season, players will likely have a rough idea of what to expect going forward.
One option for Diablo 4's seasons to consider is to explore content from past games that didn't make the final cut. Including returning features from past games, there's a lot that didn't end up making the cut for Diablo 4, although it may not be too late for some of these features to make a comeback.
Diablo 4: Every Super Rare Unique Item Explained
Diablo 4's Missing Features Additional PvP modes (arena)
PvP in Diablo 4 can be extremely unbalanced due to the lack of level-based and party-size matchmaking criteria. Given how max-level players in Diablo 4 have access to full Paragon Boards, Skill Trees, and loot, there isn't much in place to protect under-leveled players. Additional PvP modes, like an arena, could have provided a more level playing field for PvP, although Blizzard has stood by their current form of PvP, praising its chaotic nature and inherent risk involved.
Gear sets
Many players expected Diablo 3's Gear Sets to make a return for Diablo 4, although the developers have since expressed that there was no desire to do so. For every two pieces of Gear Set items equipped, up to six total, players receive increased set benefits, while there is also the option of mixing and matching different combinations of sets. Without Gear Sets, Diablo 4 allows players to have a lot more freedom with buildcrafting, in that there aren't as many specific molds to follow this time around.
Cursed Gear
Cursed Gear is a loot tier from Diablo 2, and these items are fairly similar to gear set items. The main difference between cursed items and gear sets is that the former have both a positive and a negative effect. In order to benefit from any positive effects of Cursed Gear, players need to match two or more pieces with the same positive effect, while the negative effects will stack regardless. Blizzard developers went on to state that they didn't want Cursed Gear to return in order to avoid the harsh limitations they could place on certain playstyles and builds in Diablo 4.
Charms
Another feature explicitly mentioned by Diablo 4 developers is the concept of Diablo 2's charm items not returning for Diablo 4. These items granted players varying stat bonuses just for holding them in the player's inventory. Since there weren't too many restrictions in place for how many Charm items players could hold, it ultimately placed severe restraints on the remaining inventory space a player could have. For this reason, Diablo 4 chose to avoid Charms in favor of letting players spend more time engaging with Diablo IV Items for sale content and less time returning to Diablo 4's social spaces to manage inventory.
