Bah, I could care less about revan. The only reason i'd want to meet up with him, is to kill him.
Revan sucks as a leader. For the DS male game, he returned to the Sith, but then left them in ruin, leading to their demise. Pfst, some leadership eh? I can understand Sion's rage at him.
I'm not going to slaughter the 4major sith lords during the game, and then have my character go off and serve revan. The way I see it, Revan is the exile. No longer wanted among the Sith.
