Ok, here we go again, argue with the most all-knowing of star wars ever...
1- Well, Revan was a jedi knight, who became a Dark Lord of the Sith, Darth Revan, what to me means that he is a master of the dark side and it is stated that he's one of the most powerfull sith etc. After that he goes to the light side again and became a jedi MASTER (it is stated in the novel), which again, to me, means that he is a master of the light side. So, yes he mastered both sides of the force.
About the lightsaber fighting, it is stated that he was one of the best dualist of his time, wich was a time with a LOT of fighter both from dark and light sides and mandalorians, etc. So, even that we can't confirm that he mastered any lightsaber style, he probably did, and if he didn't, there is no difference, because he's still one of the bests.
2- He was a tactical genius as stated before, praised for a lot of fighters including mandalorians that are all about war. Just because you don't think he is and have no arguments to base this doesn't means he wasn't. You must remember that we don't know the majority of things made by Revan, actually, we know almost nothing about him and there could be situations that aren't shown to players that only canderous have seen.
3- Yes, he used both sides of the force. In the same time? No, not in the same instant but he could, for example, heal his wounds with force heal (light side) and after that kill someone with force lightning or force storm (dark side). This is use both sides of the force.
Also, he isn't the only one to do that. Kyle Katarn could do that too and so luke skywalker. Although they didn't like to use dark side powers fearing to fall to dark side.
Oh, and **** G-canon, **** what George Lucas says, he doesn't even cares for what he says and the repercussion that it would have.
This is so true. The novel and the game screwed with Revan character.
1. A title does not make you a master. Darth Revan was the servant of the Dark Side, not the other way around. The only man who can claim mastery of the Dark Side is Darth Sidious. And Revan was made Jedi Master at the request of the people. Had it been up to the Jedi Council, they would have exiled him because of his teachings.
2. *cough* character statement *cough* Read my review of his tactics.
3. Revan could not control the Dark powers and would have fallen eventually. He could not even control himself, how could he control the corrupting powers of the Dark Side.
Just because G-Canon doesn't conform to your views doesn't make it non-canon.
