I'm with you there man. I've always been a huge nerd for the Warcraft lore, part of the reason why I'm so annoyed by what Blizzard's done with it in recent years. I'd love to get some decent fics from it. The only reason I can think of why there might not be any is that people have just been turned off by how silly it's gotten. Maybe there's something else, I dunno, but as you say, on the surface it seems pretty fertile ground for fanfiction.
