Have you ever considered that the Sith Empire wins in the end, but after let's say... 1 000-2 000 years there is an massive revolt in the galaxies and the Jedi help the populations destroy the Sith? Having the Sith Empire change it's power system doesn't mean it would be 100% be abolished. Just think of the Soviet union anthem... First the "new" Russia wanted it gone but then they brought it back... Same can happen! in SWTOR
I just cant see how it fits that Republic picked the hatefull Sith
LOGO as its own
Mind to tell that Palpatin didnt hate the Republic itself, just a jedies.
