Granted. But if Meetra was male then she could not have won the fight 'cause Sion would have eventually worn her (him I guess) down. See what I'm saying? Put any other Jedi in her shoes (Like Obi-wan why not?) and that person wouldn't have been able to beat Sion. Does this mean that Meetra is more powerful then Obi-wan? No.
Correction: I suppose she could have used severe force like you say.
But regardless, you see my point.
Actually, if you play the male exile, Sion will say that he hates you and you can convince him to let go of his hate, thus killing him.
Obi-Wan would beat Sion pretty easily...
