In my opinion if WoD was released in its current state (w/the exception of the raid obviously), I honestly think this would have been one of the better expansions.
Assuming of course they would continue to support it. First patch Netherstorm (whatever it was called), and the second patch that Ogre Island I remember seeing in the south during Blizzcon. Honestly if they delivered on those two content patches, and the raids that came w/them were good, IMO WoD would be right up there w/WoTLK and BC.
