Team 2 should take it. If Ventress faces Lsu it would be a stalemate so they will have to wait until the end of the battle between Shaak and Unduli. Ti impressed me more Force and Saber wise so she beats Unduli and with Asajj they defeat Lsu. If Ventress faces Luminara and Shaak faces Lsu, Ti stalemates Lsu while Asajj beats Unduli.
Round 1 Is inconclusive seeing as how prep or how I conceive it is usually reserved for darkside practitioners hehe. But seeing as how that is an open ended factor, it won't make any difference given that even with Raskta's skill she had admittedly no force abilities/dueling feats to compare with the skill of Ti or Ventress. Without her amp she can hold her own in a saber match for a while, but once Ventress or Ti utilize TK she's out.
Luminara also is no match for either of them in my opinion.
Team 2 takes both rounds.
