Tactical Genius? No. Another misconception. Revan was not a tactical genius. During the Mandalorian Wars, he used the Mandalorian tactics and superior Jedi numbers to gain victory. During the Jedi Civil War, he had Admiral Saul Karath and several other Republic officials that knew Republic tactics. Revan created tactics with Admiral Karath to counter everything the Republic would do against them. That does not make him a tactical genius. If it did, Thrawn would be a tactical god. Which he is, but a greater one going by that standard.
Really? I though he was quite the battlemaster
He did win the Mandalorian Wars after all.
xUsed both sides of the Force simultaneously? Not only is that impossible by G-canon, but it is also impossible physically, mentally, and in the Force. And no, Revan is not a special case (an argument I heard recently... you know who you are). It is impossible to use both sides simultaneously, not just because of G-canon, but also because of the toll it would take on the body, mind and spirit. It's been tried before, with disastrous results. What we have here is Revan entering a brief moment of Oneness with the Force. A moment in which Revan was enveloped into the Force and unleashed its full power.
Interesting, didn't know that. When has it been tried before?
