I think one can be opinionated and critical without being arrogant. I do not know who the author is, but reading the post, I'm getting huge Main Character Syndrome[1] vibes. I mean, calling it "The Hero's Journey"? Seriously? Sure, buddy. The world is a story and you're the protagonist hero, venturing forth among a world of NPCs. I don't care how much of a literal genius someone is: that kind of life attitude is pretty off-putting.
