FYI, I have NOTHING against furry races, I don't mind the Tauren, I have a Worgen Warrior (yeah, I know a theme I beat to death, but at least the class gives me the big sticks to do it with.

), I'm more against shoehorning in a new race of Oriental and Martial Artists into a primarily Western setting.
I mean, I love Kung Fu Panda, Po is really cool, but...
You know, the more I think on it, the more I think that one of the planets in BC's sky (go and check Hellfire Pennisula's skyline, just go through the portal and look up) could have been better used for it. THEN, I don't think I'll have that much of a problem. And WoW is kinda lucky for MMO spaces. I mean, most fantasy stories have a middle and end, very few have mutliple protagonists that operate at the same time.
Star Wars is the only other universe out there that can do MMOs, mainly because it's not limited to one planet (which only has so much space for exploring and cultures) and over the last 40+ years has had a lot of material (most of which is canon) and heroes and places to explore and see.
World of Warcraft managed to escape that by having Draenor available. Not to mention the Time Stream that the Bronze Dragons protect, and the Emerald Dream. They also have two separate 'big baddies' that they haven't completely tackled yet: The Pantheon (not so much bad guys, as factions and interests) and The Burning Legion. Hell, the BL has been a running theme through out the entire series.
They corrupted the Orcs, they created the Scourge, Sargeras (a former Pantheon groupie) is one of theirs, not to mention the mess they left behind in various times of Azeroth's history.
So much potential!
