Which version of the rules for D&D WoW is this, by the way?
I know of two, both on the link into the Blizzard store above. I rather liked the first release; the second was like a precursor to fourth edition D&D, focusing too much on abilities' icons. Sure seemed like the ideas for other areas of the books suffered due to this change in design philosophy, somehow...
The first version was pretty much 3rd edition though they added a few classes like the Tinkerer. the 2nd version of the Warcraft RPG was more Open License stuff than 3rd edition. They pretty much rewrote most of the classes and races and tinkered with the magic system to be more Mana based instead of Vancian.
Also has kind of a neat thing for tracking changes in your settlements.
I've been trying to convert it for Pathfinder on and off in my spare time. If I ever get it finished I'll probably put it into a PDF or something for people who want it
