SPOILER ALERT. So you know be advised...
Well you say you are a Revanite so you know who really leads the Revanites right? You did those missions I assume in order to claim the Title. Therefore you know that the actual Revan has nothing to do with them. My question is this. Is the real Revan leading this long hidden cult? According to the official SWTOR wiki the Order of Revan was reshaped by Colonel Darok and Darth Arkous AFTER Revan's disappearance from the Foundry. The only evidence that the actual Revan has anything to do with this cult is a massive hologram of someone appearing to be Revan. Hardly any real proof, how easy is it to fake a hologram? So I highly doubt Revan will be the one who wants to destroy the Republic and the Empire. Will you encounter him in the expansion? I would hope so but he won't be your Nemesis I believe. At any rate I won't be paying for the expansion, not because I don't like the character of Revan or think it will be any good or not. Just because my concept of Revan is female. I accept that they had to pick a gender for Revan to be included in this game and what have you, but it did not have to be male. Call it silly if you want, but it's my choice.
