Sith Stealth Class? -- Forums of the Old Republic
There's a screenshot of what appears to be a new character, who you might think was just a female Smuggler, were it not for the caption:
It takes skill to avoid detection by the Jedi.
It could just be saying that Smugglers aren't liked by the Jedi, but I don't think so... I'd say it seems more likely that this is an Empire aligned spy/infiltrator class, especially as the character in this screenshot looks exactly like the Twi'lek from the Deceived cinematic, only human.
