Come on, the quote isn't that bad. Maybe a little cheesy... he probably meant it as a joke
Oh, or imagine he gets challenged to a duel by some guy who keeps mocking him, saying that his skills are lacking and his techniques are embarassing. And Gaiden only says that sentence - right before he kills the guy with a very unspectacular thrust.
That would actually be pure coolness!
By the way, interesting to hear that there was a "Let's make the Redguards Japanese" era. Explains a couple of things.
And the Morrowind quote in the intro is brilliant.
