Why did I just quote that entire post? *shrug* My bad I just took up the whole darn page it seems.

As to Vitiate not using a lighsaber. I think its pretty safe to say that he didn't really need one. Who was going to challenge him? He had pretty much brainwashed the Sith into following him. A lightsaber would have come in handy in his fight with the Revan, but we saw that he really didn't need one.
