i remember back before launch the devs saying that Sith Sorcerer (Sith Inquisitor) was modeled after darth sidious, Sith Assassin (Sith Inquisitor) was modeled after darth maul, Sith Juggernaut (Sith Warrior) was modeled after darth vader. i tryed finding the video where they said this but no luck. : / but i think it was at a guild summit.
Yep, I remember them saying assassin was modeled after Maul, also. Hence the name of the Maul ability and the very recognizable Seethe from Episode I.
