Summary

Preparing for a new Diablo 4 season is often less about finding a stronger build and more about avoiding systems that slow down your progress. Season 15 is expected to introduce several important improvements, including Mythics 3.0, account-wide War Plans, expanded stash management, class balance adjustments, and crafting refinements. This guide walks through the proposed changes in gameplay order, helping you understand what to prioritize before Season 15 begins while keeping your Diablo 4 Items progression efficient.

Step 1: Reduce Early Character Setup Time

One of the largest barriers to creating alternate characters is having to repeat War Plans on every class.

Season 15 is expected to make War Plans account-wide, allowing progress to carry across your account instead of repeating the same objectives multiple times. This change should make leveling additional characters much less repetitive.

Another major improvement players are requesting is significantly more stash space.

With Sets, Charms and Seals all competing for storage, current stash capacity quickly becomes limiting. Increasing stash space or introducing larger stash tabs would make managing multiple builds considerably easier.

 

Step 2: Take Advantage of Mythics 3.0

The largest itemization update is Mythics 3.0.

Currently, upgrading a Unique into a Mythic through the Horadric Cube rerolls the item completely, making the outcome entirely random.

Season 15 is expected to preserve the original Unique while upgrading it into its Mythic version. Existing affixes such as Strength, All Damage, Cooldown Reduction, and Whirlwind Ranks will remain instead of being replaced by a random roll.

This makes investing in high-quality base Uniques far more worthwhile before attempting Mythic upgrades.

Step 3: Expect Better Crafting and More Meaningful Mythics

Although Mythics 3.0 solves one problem, several crafting concerns remain.

The current crafting system lacks targeted crafting, forcing players to repeatedly gamble for specific Mythics like The Grandfather instead of crafting them directly.

A return to expensive but deterministic crafting would reduce unnecessary randomness while keeping Mythics valuable.

Another issue is Mythic quality.

Current drop rates are generally acceptable thanks to abundant Superior Lair Keys, but many Mythics still roll with poor affixes, leaving players with large quantities of unusable gear instead of meaningful upgrades.

Several iconic Mythics have also lost much of their identity.

Examples mentioned include:

Oath of Perdition 

Harlequin Crest (Shako) 

The Grandfather 

Rather than increasing drop rates further, improving unique affixes would help these items feel powerful and distinctive again.

 

Step 4: Prepare for Class Balance Changes

Season 15 balance discussions focus on strengthening weaker classes instead of reducing the power of popular builds.

Classes highlighted as needing additional support include:

Paladin 

Necromancer 

Warlock 

Meanwhile, enjoyable builds such as Whirlwind Barbarian, Rend, and Charge are considered healthy choices that should remain viable.

The same philosophy applies to Sorcerer.

Instead of forcing players into a single competitive option, multiple elemental builds—including Ball Lightning, Lightning Spear, Blizzard, Frozen Orb, and Fire builds—should remain competitive throughout the season.

This approach encourages build diversity without reducing the enjoyment of existing playstyles.

 

Step 5: Watch for Quality-of-Life Improvements

Several additional improvements could make everyday gameplay smoother.

Barbarian Expertise

The current Expertise system still requires manual leveling and contains multiple bugs or inconsistent interactions. Simplifying the system and fixing its mechanics would improve the overall class experience.

Loot Filters

Players want loot filters to function consistently.

Filtered items should no longer appear in stash notifications, and additional filtering options for Seals, including six-slot Seals, would make inventory management much easier.

Echoing Hatred

Starting Echoing Hatred at higher difficulties currently requires clearing many low-level waves first.

Allowing Torment 12 to begin around Wave 100 would eliminate unnecessary waiting while preserving the challenge.

War Plans Rewards

Although War Plans provide useful gameplay effects, many rewards no longer feel competitive compared to activities such as Helltides or boss farming.

Improving reward values would make the activity worth repeating.

Mephisto Rewards

Torment 12 Mephisto currently requires valuable keys but provides inconsistent Mythic rewards compared to the Reaper boss.

Adjusting loot quality would better match the investment required.

Step 6: Improve Crafting Consistency and Combat

The Horadric Cube Transfiguration system remains heavily dependent on RNG.

Items frequently become Indestructible, preventing further improvements and creating unnecessary crafting bottlenecks.

Reducing the chance of this outcome while lowering overall randomness would make long-term item progression more rewarding.

Combat balance is another important area.

Certain Lightning affixes and on-death effects can still instantly defeat characters despite extremely high Toughness values, making survival feel inconsistent. Better balancing of these combat affixes would reward player decisions instead of unavoidable damage spikes.

Finally, many crafting materials still require manual pickup while others are collected automatically.

Extending auto-pickup to additional Horadric Cube materials would reduce unnecessary interruptions during farming sessions.

 

Key Takeaways

Account-wide War Plans would significantly improve alternate character progression.

Additional stash space remains one of the most requested quality-of-life improvements.

Mythics 3.0 is expected to preserve original Unique items during Mythic upgrades.

Class balance should prioritize buffing weaker classes like Paladin, Necromancer, and Warlock instead of heavily nerfing popular builds.

Loot filters, Expertise, Echoing Hatred, and Horadric Cube Transfiguration all have clear opportunities for refinement.

Combat balance and auto-pickup improvements would make endgame farming smoother and more consistent.

 

Conclusion

Season 15 has the potential to improve Diablo 4 through practical quality-of-life updates rather than dramatic mechanical changes. Better account progression, more reliable Mythic crafting, stronger class balance, improved loot management, and reduced RNG would all contribute to a smoother endgame experience. Before the PTR arrives, understanding these proposed adjustments can help you plan future builds, prioritize valuable gear, and make smarter decisions about your buy Diablo 4 Items strategy as the new season approaches.
