@Deonyon that's a fairly big blanket statement, brother.
My assumption is you're referencing xuanhuan and modern xianxia, because the chances of you finding young masters who have a need to make snarky remarks in wuxia is 1/20. I'm being extremely generous there, because it's more like 1/30. And when you do find them, you've got, at most, 2 arrogant young masters in them. As for traditional xianxia, never seen an arrogant young master.
