B. Resource Systems
Fury, Mana, and Other Resources: Certain classes rely on Diablo 4 Items specific resources to fuel their abilities. Adjusting how these resources regenerate, how they interact with skills, and how efficient they are is common. For example:

The Barbarian might need changes to how quickly they generate Fury during combat.

The Sorceress may require adjustments to mana regeneration or mana cost reduction to make their abilities more sustainable.

Resource Management: Some classes may feel tedious or awkward due to poor resource management. Reworking a class's resource system can help reduce frustration and increase the fun factor.

C. Passive Skills and Traits
Improved Passives: Adjusting passive abilities and traits can help classes remain useful in all content, including endgame. For instance, adding more synergy between passive abilities and core skills can make for smoother gameplay.

Buffs and Debuffs: Reworking passives that apply buffs or debuffs to either the player or enemies can help a class adapt to new content or fix issues with class performance.

D. Defensive and Survivability Skills
Health Scaling and Damage Mitigation: Reworks often involve improving a class’s defensive capabilities, particularly if it struggles in harder content. This might include adjustments to shields, armor, or damage reduction abilities.

Healing and Sustain: Some classes might receive improvements to their self-healing or damage absorption abilities to improve survivability in high-level content like Nightmare Dungeons or Raids.

3. Specific Class Reworks Example
Let’s take a closer look at how specific classes might undergo reworks or adjustments:

A. Barbarian
Resource Changes: The Barbarian's Fury system may be adjusted to make it easier to manage in combat. If players report that the Barbarian’s Fury generation or expenditure isn’t smooth, the resource economy could be tweaked for more efficient combat.

Skill Synergy: Improving the synergy between Weapon Mastery, Shouts, and Weapon Skills would make the Barbarian more versatile and allow players to mix and match different playstyles.

Survivability Buffs: Increasing defensive abilities, like the Iron Skin skill or improving damage reduction when in Berserk mode, could help the Barbarian survive tougher fights, especially in Diablo 4 Items for sale endgame content.
