There's NO way anyone in the Empire would join him; he was attempting genocide against trillions of people -- 97% of the Empire's civilians.

That's from a world quest, not a class quest; and if you don't constantly pick Dark Side it's a perfectly reasonable affair.

The reason that HUMANS believe they are above all other ALIENS (NOT Purebloods) is because 97% of HUMANS in the Empire can trace their ancestry back to PUREBLOODS. ONLY HUMANS can trace their ancestry back in this way, and thus some HUMANS have convinced themselves or been misinformed that HUMANITY is synonymous with their lofty positions within the Empire. At the root, it's about their proximity to Purebloods -- but that evolved into a humanist ideal over time as alliances were made and HUMANS belonging to the Empire and Republic became indistinguishable. Someone can't tell how much slight Pureblood ancestry a human has by looking, so they can't spend the time finding out -- they just go the speciesist route. You wont find a SINGLE instance of HUMANS being speciesist against a PUREBLOOD, because they all know better (minus instances in the Sith Inquisitor story, because Purebloods were made playable for them later, and they are still slaves).

I lost all faith in what little I believed you were basing your arguments on facts rather than guided emotions...

Um, guy, what you dont get is that (at least for synthweaving) there's no POINT in those augment slots when the very easy to get PVP and raid gear, by default, has SO much more stats by default than the mastercraft armor etc. Even if I crit on all of the slots for mastercraft helm, shirt, pants, gloves, boots, belt, and bracers, the PVP/Illum gear is still better anyway, so there's no point.
