Precognition isn't that useful if you're too slow to actually do anything with it. Knowing where Bane will strike doesn't mean that Revan would be fast enough to put his lightsaber in the way before Bane cuts him down.
You really doubt Revan's speed, don' you? Also, he would know where Bane would strike several attacks ahead of time, not a few mili-seconds before. This is not a "auto-win" as some make it out to be, but it should be able to allow him to hold his own against Bane in terms of lightsaber abilities.
"It is the way of the Echani to be able to read their opponents - to know where an opponent is going to strike before it connects, anticipate it, and then strike against them. Echani battles are fought several minutes in advance - in many ways, it is much like the game of dejarik played in the core systems. The most advanced among the Echani are able to predict the course of battles by months, and the most revered are said to be able to predict the path of wars. Only Revan ever demonstrated such a skill in war. And even as he slaughtered us, the Echani still respected him."
Bane didn't actually kill Raskta, Zannah stabbed her in the back.
This isn't helping your argument.
That was Jedi Malak before the Mandalorian Wars even started.
No. Malak vs Mandalore happened in 3963 BBY.
That Malak also got beaten by Jareal in training, he was a total assclown.
Under the circumstances that he was flirting and teasing (not even joking, look at the fight)with Jareal the entire fight.
Gee, maybe it was because Revan had the Force and Mandalore had an axe. Just a suggestion.
Despite this, Mandalore the Indomitable is still able to hold his own against Droma and Ultimate is able to whoop Malak's ass.
This is not even mentioned Mandalore's armor is made with lightsaber-proof material. It is extremely difficult to overcome it.
Defeating non-force sensitive Echani doesn't even compare to defeating a Jedi Master Echani.
*Defeating hundreds of Echanis who are masters of precognition.
No. Bane would demolish Revan in a lightsaber fight.
If Revan is capable of holding off Nox and Wrath at the same time, while having grenades and blaster fire sprayed at him, I beg to differ. Bane was not capable of defeating Zaanah.
