We know of the capacities of NJO Luke, Yoda, Exar, Revan, and Mace.
We have relatively little knowledge of Sadow and Ragnos in combat. Yes, Sadow made a star go supernova, but so did Exar, it's uncertain just how deep and powerful their capabilities would be.
However, because it's 4v3 and practically everyone in this fight is capable, assuming that Sadow and Ragnos don't possess some unseen godly powers, I would have to play the numbers game, even if it may be close.
