Of course you of all people is going to agree with Ant, Aurbere. You're like Gokudera to his Tsuna, KEK.
Luke was far from his prime against Desann - and he didn't really do shit but shove him and run afterwards. Plus, Luke's holds back in proportion to who he's facing - no way would he hold back to the same extent against someone as dangerous as Revan.
Edit: Also, what DMB said about the Lumiya thing.
Luke didn't lose to Desann, though - the latter just ****ing shoved him and ran away afterwards KEK. Luke's inconsistency is there because, he holds back to a significant degree because of his brushes with the darkside, as stated in like, 3-4 different sources. By himself, Mara Jade, and the omniscient third -person narrator.
Skywalker pushes Revan's shit in.

This ****er wasn't stomping Revan. You think Luke w/ morals could?
