Revan did not "master" any sides. Mastering either side of the Force requires conviction. Revan has no conviction in the Force. He constantly flip-flops on what side he uses, never being capable of mastering any side. Very few Jedi/Sith have mastered an aspect of the Force. Revan will never reach that goal either.
2. CHARACTER STATEMENT!
I think I covered the misconceptions very well. That's what i set out to do. You're just upset that I haven't conformed to the "Revan is god" ideal yet.
Constantly flip-flopped? He flip-flopped #1 time.
Revan has no conviction in the force? Sounds like speculation.
