Patch notes Oct 8 – Part 2/2: Classes
⚔️ Rage for Warriors and Druids
- Several bugs with rage from damage taken have been fixed: until now, more Stamina meant less rage, critical and crushing blows were counted incorrectly, and absorbs were included.
- Rage is now tuned for 20–40% armor (depending on level) instead of 50% tank armor. Questing Warriors and Druids get noticeably more rage as a result.
- Demoralizing Shout now generates threat; Arms: Deep Wounds is once again a prerequisite for Impale; Protection: Last Stand grants the correct amount of health again
🐻 Druid
- Critical strikes grant 100% more rage (was 75%), Bear Form generates 50% more threat (was 30%)
- Mana potions usable again in Bear and Cat Form, Cat Form no longer lowers maximum health
- Thorns: base damage as in Classic, spell power coefficient 6% (was 13.3%)
- Feral: Predatory Instincts is now called Natural Instinct and additionally increases healing by 12/25% of Intellect
🏹 Hunter
- Disengage now reduces threat twice as much, as originally planned
- Survival: Expose Prey lasts 10 s (was 5 s), Entrapment now only when Frost Trap is triggered and with diminishing returns
- Beast Mastery: Unleashed Fury now actually increases the pet's damage
🛡️ Paladin
- Retribution Aura now uses your own spell power, base damage as in Classic (about a third less), spell power coefficient 6%
- Protection: Reckoning triggers at most once every 1.5 s; mana from Seal of Fury talents no longer generates extra threat
✨ Priest
- Discipline: Penance deals less damage and healing (it was calculated like a 3-second channel), costs more mana, ranks 2 and 4 heal more
🔥 Mage, ⚡ Shaman, 💀 Warlock
- Mage: Impact no longer triggers from Flamestrike's damage over time
- Shaman: Elemental Focus is no longer consumed immediately by Fire Nova, Mana Tide Totem visible again
- Warlock: the old demon is stunned when a new one is summoned
📈 Spell ranks
- The low ranks of many baseline spells have been adjusted, for example Frostbolt, Fireball, Smite, Lightning Bolt and Shadow Bolt. Every new rank is now a real upgrade.
⚠️ What this means for you: New spell ranks from your trainer are always worth it. Warriors and bear tanks have far fewer rage problems.
