NJO Luke vs. Count Dooku, Tulak Hord, & Exar Kun
NJO Luke is at the same skill he was when he faced Overlord Shimrra. Stated by Jaina Solo as moving so fast it seemed he was using 25 lightsabers, and this coming from a Force-User, not by your average witness.
Count Dooku is in his prime, ROTS, as we've seen him.
Tulak Hord is in his prime, whatever given time period that is.
Exar Kun is at the same skill level he was when he killed Vodo and the entire Senate. He is wielding his double-bladed lightsaber.
This fight is saber only, however, combatants can use the force to enhance their abilities and replenish their stamina, but not heal themselves. The only other allowed Force ability is Force Jump, no push, pull, lightning, choke, etc.
This fight takes place in the middle of the Tatooine Desert, Luke starts in the middle, with all three combatants surrounding him in the form of a triangle.
