I've been with Bioware's vision since KOTOR. The Rakata have been an interesting creation that, while used, has also been neglected. I'm surprised that certain ideas (make the Rakata a playable race or perhaps a companion, have an expansion dealing with an ancient Rakata/Rakate threat) have not been used. Such would have been more interesting than Vitiate's hobby as a benevolent ruler. Vitiate's reveal to be an ancient Rakata (likely following the discovery of a mind prison or locked in an ancient prison) would have been an excellent means to reveal how he is so powerful, knew of the Star Forges, etc.
