Post ROTJ skywalker was boring to me too.... But he did have flaws, especially when he nearly had the crap beaten out of him by some random Sith in the FOTJ series, Palpatine handing him his *** in DE, Exar kun ripping lukes spirit from his body.
Luke has far more flaws than Revan.
hmmmmmm. I doubt that Luke has more flaws then Revan.
Luke may have been beat up a lot, but if so, then he was facing tuffer opponents.
