Eh? Sounds like an NLF. I mean, if we're assuming they're in character/morals on, I doubt Revan can or would pull that everytime Krayt gets close.
Now if you're arguing that Krayt won't get close at all, that would imply Krayt isn't just as, (imo more) powerful than Revan and capable enough to close the gap, especially if you're considering game mechanics, (Revan seems to get up close and personal/use his light saber skill a lot more in SOR than, say, in the Revan Novel or on the Foundry).
Well, I'm not confident Darth Krayt can use Dark Transfer without getting his hand through an opponent's defenses. Otherwise he would be sliced up.
Revan's lightsaber prowess, especially considering precognition, should be sufficient enough to keep Darth Krayt from piercing through his guard.
In a scenario where Darth Krayt does get through, which would be rare, Revan should be fast enough to teleport away to safety several meters away.
Or, at the very least, Revan's willpower should be sufficient enough to withstand the Dark Transfer for enough seconds to then be teleported away.
1. Agreed, though he can certainly accomplish such.
2. Eh? While Revan's undoubtedly an excellent swordsman, Asharad Hett was putting AoTC-era Anakin on his ass and landing physical blows on Obi Wan Kenobi, obviously waaaaaaay before he reached his peak. While the former is no Revan and Hett ultimately lost the latter conflict, I think it's reasonable to assume Krayt at his peak can break through Revan's guard in lightsaber combat.
3/4: Which, as I mentioned in the previous post, is an NLF, at least by the way you're making it sound.
I said that in a thematic sense, Revan is the embodiment of everything special in his era; he inherited it all. In that way, I related his will-powered zombie-like return from the nigh-grave to Sion; I didn't say I was behind the idea that Revan could endure more than Sion. Nor have I ever been behind the idea that Sion truly couldn't be stopped without his consent in the first place.
