YMMV / One World

• Base-Breaking Character: Depending on who you ask, Ron is either being treated unfairly or too nicely. Some believe that, Ron, despite his flaws, doesn't deserve the author's harsh judgment. Others believe that Ron is an inherently bad person whose relationship with Hermione will inevitably turn toxic and abusive.
• Broken Base: Naturally, the author's decision to go for canon pairings inspires this, but not entirely for the obvious reasons. After the first round of complaints, the author said that he'd be sure to portray Ron as "a prat and a git," but not a Death Eater, who would take longer to become friends with Harry than in canon. This divided the readership into a few groups- 1)Those who consider his analysis fair, and believe that it's best for Ron as a person and character. 2)Those who think that the author's being too hard on Ron and/or doesn't understand Ron's better qualities and reasons for his behavior. 3)Those who think he isn't being hard enough on Ron, and that any relationship he has with Hermione is doomed to failure or worse. 4)Those who are confused by his intentions, particularly writing off Ron as a bad person but pairing him with Hermione anyway (this can overlap with #3).
• Fandom-Specific Plot: The one about a sect of uber-powerful magical people who basically are to wizards what wizards are to Muggles but it's about IQ style tests. There's even an hiearchy of power with Archmages being the most powerful and squibs and muggles being those that low incidence of magic.
• Ron the Death Eater: The author implicitly references this trope by name while expressing a desire to avoid it. The fanbase is divided over whether, and to what degree, he succeeded.
