I gave the WoW RPG a miss for exactly that reason. With 3PP, it really helps to know what they're trying to do with the book and then read a review or two before spending the cash. Some are exceptional, like Tome of Horrors 1 - 3, The Book of Fiends, Ptolus, True20 (which is mostly SRD), Darwin's World, the Freeport books, and of course Pathfinder. Other stuff seems like it needs to go back for more conceptualizing before they put it out there, and I'm not naming the products that I own that fall into this category.
I own the WoW RPG too. I read it more of how the "SRD fits the WoW" world rather then a verbatum copy of the SRD. Lets see, character creation, WoW races, WoW classes, WoW equipment, WoW spells, powers, feats, skills, etc...
Yep, looks exactly like I would expect a D20/3E adaptation of WOW to look. None of it looks like a copy and paste of the SRD to me. Since you said White Wolf I can only assume you have the same version done by Arthaus that I do.
Of course I wouldn't want to buy the WoW book and then have to look up the SRD on line to find out how feats, skills, bull rush, AoO, etc... works. I would much rather have that in the book I am playing from. You know, complete. Right there, in that book. I wouldn't want to have to reference the 3E PH either.
Fortunately for me I feel that is what I got. It got me to buy several of the other books too. So the WoW books work for me.
I'm also glad that Mutants and Masterminds and True 20 repeated all of that for me in the one book too.
Its also why I hope the 4E GSL rewrite will allow 3PP to publish monster stats, spells, etc... in the books they do, I don't want to have carry around multiple books. That is part of the big covenience of modules. All I need is the module, the PH, and maybe the DMG. The monsters, and new stuff are all in the module.
Then again, that is not a big issue for me anymore, I don't go to other homes for games anymore. So now its cool for me to need to refer to all 9 of my 3E monster manuals, because they are all right there next to me on my book shelf.
However, if I was still running games at other peoples homes, or the LGS, I would want as much as possible to be covered in that module, or in as few books as possible.
So I was happy with how they did WoW.
