I personally enjoy the abundance in versus threads.
On-Topic: team 2. Oppo and Yarael are too powerful, and the former has massive saber skill hype. Piell has a bunch of good dueling accolades, and Gallia's feats need no mention. Stass though, to my knowledge, has nothing aside from Jedi Master and High Councilor hype, which is still quite good. Collectively, they're better. Especially if Oppo or Yarael step back to use BM.
Jerec and Desann are better swordsmen than their opponents, but given that one of them will have to deal with three opponents at the outset of the fight, I think the Jedi command a majority here. The Force round is a firm win for the Jedi - Yarael Poof is the star player here. The all-out probably follows a similar course to the duel.
Team wins the majority. Poof and Rancisis are two powerhouses of the force, Gallia and Piell are pretty good duelists on their own right, and Stass Allie is more a healer than a warrior, so she might be helpful.
