Aside from the fact that these guys, (IF all of them came with you) would be outnumbered a 200 to 1, I doubt whatever they had would save their asses. If anything the team is outnumbered. It was only because of Revan that they made it through the entire endeavour alive.
This is exactly the problem with the situation you're imagining.
They are not outnumbered 200 to 1 if the Dark Jedi are coming in small packs of 2 and 3, which is precisely what happens in the game. Although you could dismiss this as a gameplay mechanic, it is not a variable. In any playthrough, you will not have to fight more than 4 or 5 at a time.
Too bad Malak sent everything he had at once in order to subdue Revan.
Incorrect. He ordered them all to attack at once. Unless they all start from the exact same point and travel together at the same speed and attack at a proper point (as in, as long as they dont get stuck in a doorway or anything while Revan's crew opens fire), they are not going to be outnumbering Revan's forces 200-1. That kind of situation would require proof. It's more than possible that Dark Jedi were scattered around dozens of training areas, mediation rooms, etc all around the space station in groups of 4 and 5. Notice how they come from several directions, in the game.
Where did you guy that figure, anways? There was an undisclosed amount of Dark Jedi (mostly apprentices) on the Star Forge.
By the end, his entire army of Dark Jedi was taken down.
Do we know that?
