This is my thought as well. Who ever said all the Old gods are evil? How many old gods are there? The Earthmother could have easily turned Ammunae's Earthen into tauren with her own Curse of Flesh.

We could also see a tie between faceless ones and tauren. Could Tauren be purified faceless ones?

The only evidence we have that the Old Gods were *originally* evil is the somewhat unreliable word of the Titans' servants on that topic -- and, even there, the evidence is somewhat sketchy, as the Old Gods are described as being "incomprehensibly evil" by the Titans. I think the "incomprehensibly" part there is fairly important, as it sets up the very real possibility that the Titans and the Old Gods clashed not because either side was fundamentally evil, but their natures were too alien from one another to allow comprehension and mutual co-existence without conflict. Order cannot understand Chaos and all that.

OH, LOOK, AN OVERARCHING UNIVERSAL THEME.

Which is not to say that the Old Gods involuntarily imprisoned in/on Azeroth know aren't demonstrably pretty freaking evil. They *are* that. But I imagine that being imprisoned on dubious grounds for an unimaginably long period of time with your sole goal being to get out and take vengeance on the things that put you there isn't exactly conducive to maintaining a constructive worldview. Or, y'know, sanity. Whether that was *always* true is, however, substantially debatable, especially given that the Titans effectively wrote all the history books -- and their own servants do not exactly paint the Titans as completely devoid of morally questionable facets, what with that whole "destroying whole worlds that deviate from acceptable normative development" thing.

Personally? My ultimate Tinfoil Hat Theory is that all the sapient species of Azeroth are different and special because they combine and harmonize aspects of the Titans and the Old Gods into a functional whole. The orcs and draenei, being not actually of Azeroth, are special because they were both races touched by the true ultimate and destructive all-devouring evil of the universe -- Sargeras and his nihilistic desire to pervert everything into a twisted reflection of his own corruption -- and each escaped it in their own way, to warn other worlds by example (the orcs) and by word (the draenei). Sargeras' minions keep getting their heads handed to them by Azeroth because the union of the primal creative forces of the universe cannot be overcome by the mindless urge to perversion and destruction.
