Across the board
- The resistance racials are gone. Dwarf Frost, Night Elf and Tauren Nature, Undead Shadow and Gnome Arcane Resistance (+10 each) were cut.
- Weapon skill became crit. The +5 weapon skill racials that stayed turned into crit chance with that weapon type: Human swords +2%, Orc axes +1%. Dwarves get a new +1% with maces. Human maces, Dwarf guns and Troll bows and throwing weapons were dropped.
- Six new pairings: Human Hunter, Orc Mage, Dwarf Shaman, Undead Paladin, Gnome Priest and Troll Warlock.
Alliance
- New:
Will to Survive, removes all stuns (3 min cooldown). 
Sword Specialization: +2% crit with swords instead of +5 sword skill.- Gone: Diplomacy (+10% reputation) and Mace Specialization.
Stoneform: still clears Bleed, Poison and Disease, now with 10% less physical damage taken instead of +10% armor.- New:
Big Game Hunter (+5% damage to Beasts) and 
Mace Specialization (+1% crit with maces). - Gone: Frost Resistance and Gun Specialization.
Quickness: +2% movement speed on top of the 1% dodge, and the Rogue and Druid stealth bonus moved here from Shadowmeld.
Shadowmeld: usable in combat to drop threat, at the cost of a 2 min cooldown.
Wisp Spirit: 75% speed as a wisp (Classic 50%).- New:
Elune's Light, +10% crit for 15 sec. - Gone: Nature Resistance.
Escape Artist: also grants 3 sec of immunity to movement impairing effects, and the cooldown doubled to 2 min.
Expansive Mind: +5% max mana instead of +5% Intellect.
Engineering Specialization: 20% fewer engineering device failures instead of +15 Engineering skill.- New:
Eureka!, cheaper and stronger next 3 damaging abilities. - Gone: Arcane Resistance.
Horde
Blood Fury: +10% attack power and spell power for 15 sec, with no healing penalty. Classic gave +25% base melee attack power and cut healing taken by 50%.
Hardiness: stuns last 20% shorter instead of a 25% chance to resist them.
Axe Specialization: +1% crit with axes instead of +5 axe skill.- New:
Shatter Curse, clears and blocks Curses and cuts magic damage taken by 15% for 8 sec. - Gone: Command (+5% pet damage).

Berserking: one version for every class at a flat 10% haste. Classic had three class versions that scaled from 10% to 30% as your health dropped. Its tooltip points at a duration spell Forever removed, so the game files don’t show how long it lasts (Classic: 10 sec).- New:
Rapid Regeneration, 50% of max health over 6 sec, broken by any action. - Gone: Bow Specialization and Throwing Specialization.
