Barbarian — Whirlwind with Infused Weapon Catalysts
Barbarians still dominate melee, and Diablo 4 Items the addition of weapon-infused Horadric Spells adds burst damage and utility. Whirlwind remains the go-to, now empowered with Catalysts that add knockback or stunning effects.

Why it works:

High mobility combined with sustained AoE damage.

Horadric Jewels further enhance survivability or damage.

Great synergy with existing Barbarian passives.

3. Rogue — Shadow Trap & Multi-Arrow Builds
Rogues excel with a mix of traps and rapid-fire skills. The PTR’s addition of Horadric Powers that augment Shadow damage and debuffs makes Rogue builds versatile and deadly.

Why it works:

Debuff Arcana stack well with rogue crit-based playstyles.

Traps combined with Catalysts create devastating area control.

Mobility and survivability remain high.

Season 9 PTR Losers: Builds Facing Challenges
1. Druid — Elemental Shapeshifting Weakened
Druids relying heavily on shapeshifting and elemental summons have seen their core skills suffer from nerfs or diminished scaling with the Horadric system.

Why it struggles:

Some key passives reduced in effectiveness.

Elemental infusions compete poorly with direct damage Horadric Powers.

Summons have reduced synergy with current Jewels and Arcana.

2. Necromancer — Bone Spear & Corpse Explosion nerfs
Necromancers still pack a punch but face slower clear speeds. Bone Spear and Corpse Explosion, once dominant for AoE, have received damage nerfs, pushing players to adapt.

Why it struggles:

Heavy reliance on corpse mechanics now bottlenecked.

Horadric Powers for Necromancer lack some of the damage punch of other classes.

Scaling issues with cheap d4 mats new itemization.
