Luminara Unduli v. Jaina Solo v. Asajj Ventress

Each at their best. Takes place in the Jedi temple.

1.Lightsaber battle
2.All out

I really don't know how powerful Jaina Solo is, but I do believe Ventress is more powerful and skilled than Luminara Unduli.
If this is a free-for-all match, then this would probably go to Ventress.

I would assume Jaina Solo is a good duelist else I wouldn't believe Luke would have brought her Along in the final Duel in the Vong Wars.

But speculation.

Do we really know enough about her to debate about her power?

Luminara Is better than both of them anakin beat ajass when he was a padawan Luminara is a master. Jania Probably could of beat Ajass Ventress 2. But jania v.s Luminara, iam not sure

Then, by your logic, how jedi knight Anakin beat jedi master Cin Drallig?
