🙂 My theory! Hold on. . .
"I personally have to give Mace a better chance against Revan than anyone featured in the movies. Not because he is superior to them, but because of his fighting style. Now, while obviously an extremely skilled duelist on his own, it's Revan's remarkable precognition that allows him nigh invincibility against most. Now, people who disagree with this are either going to have to choose from two options concerning the Dark Lord:
1) The theory is correct; Revan's pre-cog is one of the major factors in his dueling skill, not Force abilities, but the ability to win a duel.
2) The precognition really isn't all that great, and so does not help very much in a duel.
Now, the reason that Revan's precognition is important in this argument is because of its characteristics. "Tactical Prediction", right? If so, Mace has an excellent chance of staving him off for a time because of Vaapad, the form that completely defies prediction. It is unpredictability in raw form, wielded by arguably the most talented swordsman the Jedi Order has had in its ranks.
If option two is chosen, then Revan's precognition is not as effective as many of you seem to claim.
I'd personally go for #1, since of course, it is my theory.
Now, nobody misunderstand me here. I am in no way saying that Mace would defeat Revan in a duel. But he would give Revan some trouble, seeing as how his unpredictability in Vaapad nearly nullifies Revan's precog advantage.
And it helps to have three mastered forms (Ataru, Djem So, Juyo/Vaapad) to call upon in a duel."
