Malak is better than Dooku, and he could eat OT Vader for breakfast. But I don't think NJO Luke has this as a walk in the park. I mean, the ghost of Exar Kun gave him fits. Add Dooku, a master of a lightsaber form Luke has never seen (And one dedicated to defeating other lightsaber duellists), his father (Whom he wouldn't want to kill anyways... And besides, if you guys are gonna use that "The Force is his ally" plot element/pinch hitter deal, then you have to bring in the "Chosen One" theory, add that Luke would be conflicted to fight his own father, etc. etc. Don't use bias in building arguments. I haven't seen one reason as to why the others would use other than the usual "NJO LUke is god". And you know why NJO LUke is suddenly god? Because ROTS proved Anakin Skywalker can't hack it like everyone thought he could. End rant)
Now, Malak himself is a Sith lord. He managed to remain undefeated in the yer following Revan's disappearance, meaning he had the Force mastery and saber skills to defend his reign against any who thought they had a chance. Malak himself is a war hero and killer of Jedi. He's an impressive adversary, and his sole loss is to Revan.
Dooku, despite being rather easily punked in ROTS, is still one of the most capable duellists of his time, and could hang with Yoda (Whom I believe could give Luke a hell of a time. Yoda is THE man) His Sith powers would also add to his deadliness.
Tack on Darth Vader, someone who has mastered Luke's own fighting style and is still a Sith lord in his own right, and NJO Luke is toppled.
I know many of you love NJO Luke, I respect that. But make some reasonable arguments. This is The Last Jedi versus an ancient Sith Lord from the Golden Age of Sith, the best duellist of his time, and Luke's own considerably powerful father.
