We already know that D4 has seasons that run for 3 months and we know that the 2nd expansion is coming in 2026.
So what else would you like to see added to the game. I am not referring to balance patches or bug fixes.
I would be interested in character packs like they did with the D3 necromancer. 
I honestly think they delayed second expansion to 2026 because this year we will get GTA 6, new Borderlands and other amazing new games from epic IPs like Doom.
The Developer team can take the time to fix all the bugs and create a good foundation for the next Major Expansion.
Well, my hope is improving the systems that they already have in play to the standards of where the game has evolved to. They stated somewhere within these past couple of seasons the focus would be improving the systems they already have. So for me, what I’m hoping for:
Paragon Rework/Glyphs at least reworked to be account wide, and remove multiplicative damage bonuses until they are legendary to give more variety of use besides choosing what is just going to give you the most damage.
Improve Pits, adding leaderboards that keep records of each past season, showing you what your accounts top clears were from previous seasons (Sort of like how I can check my prior season records from my account on D3, even if that character has been deleted). Improve use of Shrines (Conduit…) more variability in the maps, new monster affixes, cut back on the damage resist auras, etc.
Link Endgame content/Seasonal content in better flow.
I think Itemization needs another revisit.
With that being said, I wouldn’t be surprised if they add Witchdoctor class into the game before expansion based on this seasons powers.
I would like to see summoning mats removed, or combined into 1 material. And then a whole horde of new, challenging bosses added to the game.
Nightmare dungeons reworked to be ‘nightmarish’ with more risk/reward. And no doors.
Want to see other end game activities scale like Pit. Better yet, want to see a non-Candyland mode.
No more paid expansions unless they are truly amazing. Seriously.
one season per year adding major game improvements and the others adding stuff that has a real chance to stay in the game. POE set the model for this and this game makes a lot more money than POE.
They have been happy to push out minimally viable products to the sheeple. If next season is just a reskin of a past season I don’t see myself bothering.
Also, they should make pits JUST for leveling glyphs and epeen pushing. Add other content for XP and loot. Preferably a deep endgame system with choices ala the POE Atlas.
Balance Patches and Bug Fixes.
No but seriously I want our Campaign Cycles back with difficulty settings based off of the New Game Plus Cycles. They can still let players skip the campaign. Go straight to ‘end game’ and base the seasonal journey and battle pass on the current systems we grind.
I’d like to see them remove the multipliers, balance all of the skills and aspects to be viable for that one difficulty and make it a well balanced experience regardless of your build choices. Then after the foundation is set they can scale up from there. Higher new game plus campaign cycles with higher item power to chase, maybe start dropping certain things exclusive to the progression cycle.
I liked this idea about Tempering Scrolls being unlimited use BUT they are the only way to add Tempers onto gear. Made a bit rarer like Exalted Orbs. So 1 Scroll drop = 1 Temper on any piece of gear. You can overwrite tempers as many times as you like using another scroll. So it’s this rare power boost for your gear, an exciting to see drop that fires something up in your brain making decisions like saving it for a better piece of gear or slapping that boost on right away. Which piece of gear should you do first? Which Temper? That would hook.
Now maybe bring this idea forward into the Campaign Cycle New Game+.
Maybe the Default Campaign/Difficulty, the universal for seasonal content and battle pass progression, you don’t even get tempering scrolls to drop. Everything is again balanced for a good universal experience regardless of build choices. Cut some of the fat off to get the game balance under control.
Then after you complete the default difficulty to move into the next campaign cycle/skip to end game+, then those Tempering Scrolls start to drop.
This could even replace the higher item power chase so that you don’t need to replace any of your current gear (dads) but continue to build onto that gear during this next Campaign Cycle / NG+
Cycle 1 - Balanced Experience. No multipliers, get everything working well.
Cycle 2 - Tempering drops unlock additional power to combat increased difficulty.
Cycle 3 - Great time to introduce Master Working after all that Tempering.
Basically I want the balance to get in a good state and I want loot to be exciting.
I just don’t see them ever getting things under control with the difficulty slider and all of the different things players are in control of right now.
Skill Tree, Paragon Board, Gear Traits, Greater Affixes, Aspects, Gems, Tempering, Master Working, Seasonal Powers. etc. It’s all too much at once to try and get a good balance to the game. We cannot find a good risk vs reward setting for ourselves we need some level of crafted experience.
Take it back to Campaign Cycles and design a way to introduce all of these things spread out over time to combat the increases of difficulty instead of having all of these systems over lapping immediately.
For the player experience as well as for the dev team to gain control again.
technically, every software engineer in the studio is capable of fixing any bugs in the game.
but 2 years down the road, this hasn’t happened due to poor direction from team leads.
so, blizzard should lay off these underperforming team leads as part of the roadmap.
I might be contrarian to whats popular around here but:
Some d3 features:
Some d2 features:
We definitely need better social systems, character customization options and codex / inventory upgrades (In my opinion)
Forget any roadmap of new content until the content we have now and the content released on seasons actually works.
