You would probably have better luck going after new games as opposed to WOW. There are multiple games just released (Vanguard) or about to release this year (Warhammer, Age of Conan). You would just have to find competent gamers that could write the guides for you.

If you have any MMORPG related questions feel free to PM me. I have played or beta tested about every game made to date. I also used to make a majority of my income from MMOs.
