The new World of Warcraft RPG is an OGL game (you don't need the PHB, and it replaces the original Warcraft RPG book).
Changes include:
- Two magic-using classes, each with three paths: Arcanists (Mage, Necromancer, Warlock) and Healers (Druid, Priest and Shaman).
- Spells mix mana and spell slots/preparation.
- No more "LA +1" races. All races start at the same power level, but some races (Ironforge dwarves, Night and High elves, Tauren...) have racial levels (inspired by Arcana Unearthed/Evolved).
- Streamlined and clarified Technology Rules for building tech devices.
- Rules for building and maintaining communities, reflecting the feel of the Warcraft games. These seem to come from Gamma World.
The book replaces Warcraft RPG, but the other books (Manual of Monsters, Shadows & Light...) are still useable. Updates will either be included in WoW RPG or in web-enhancements.
The catalog comes with the Night Elf racial levels (3 of 'em, get Shadowmeld at 1st level, Energy Resistance (fire and cold) 2 at 2nd and +2 Dex/Agile feat at 3rd; all IIRC).
