Rework Example:

Introduce more Essence generators that also interact with Corpse Skills. For Diablo 4 Items example, Corpse Explosion could have an additional benefit like regenerating a small amount of Essence for every nearby corpse.

Skill Synergies: Rework the synergy between Necromancer’s curses (like Decrepify) and Corpse Skills to further improve damage output.

C. Survivability and Damage
Current Issue: Necromancers are often weak in terms of personal survivability as their minions do not always absorb enough damage.

Rework Example:

Give Necromancers a more significant self-sustain mechanism. For example, casting Bone Armor or Blood Rush could give the Necromancer an automatic healing effect based on damage dealt.

Rework Bone Golem to grant temporary damage reduction to the Necromancer as it absorbs damage.

Summary
These rework examples for Barbarian, Sorceress, and Necromancer focus on improving resource management, combat synergy, and class-specific survivability. Blizzard typically focuses on maintaining a delicate balance between enhancing a class's core identity and addressing gameplay issues raised by the community. As Diablo 4 continues to evolve, the rework of these classes is crucial for keeping the game fresh and balanced for both PvE and cheap Diablo IV Items PvP experiences.
