What the fuuuuuuck are you saying? Just having energy and force resistance doesn't make you highly immune to force attacks. It depends on the strength of the user and attacker. Sidious would tear through their pitiful attempts at resisting his attacks like a soggy condom. Revan, being much more powerful than the asshats on the SF, would be more than capable of tossing them around or ragdolling them.
You underestimate the power of the Star Forge and those "highly skilled" Dark Jedi, but quite frankly, I'll concede, since I'm to busy typing an email to 15 BioWare people on Revan's lightsaber abilities.
But it's not a lightsaber feat. no expression
Then it's not a Force feat either.
