We saw Durge get slashed over and over again by four different Jedi for quite some time with no ill effects. Durge is also very damn fast and most force abilities don't work on him. Revan's a dead man against Durge. And Durge's mass actually regenerates flawlessly. A few saber slashes won't do anything. Took a sun to kill him
Lightning has almost no effect on Durge but pain and revan's got limited stamina. And Force storms? HAH! Prove Revan knew lightning or Force Storm, he's lightside canonically. And 'force storm' in KOTOR is 'powerful burst of lightning.' All it's going to do is hurt Durge, it won't take him out and when worst comes to worst, he'll have a furious Gen'Dai charging him....the strength to lift a spaceship and the speed to blindside six Jedi on Revan....I pity him
And, ahhhh....more BS about Revan> All the old Jedi. Nothing to support that all. Never any proof on what Revan did and how he did it.
