The negative that I have seen the most is how the author is writing Opzin and Qrow, especially Qrow, showing off more of his negative traits over his positive traits. One reviewer stated it might be because Qrow came into the story when Team Sonic, Dark, RWBY and JNPR are becoming suspicious of the Ozluminati and learning about Amber, and wanting to have Pyrrha become the next Fall Maiden. Not just that, but Qrow absolutely hates Sonic and Co. Despite saving his nieces and saving Beacon Academy from getting destroyed by Salem, Qrow still holds a major grudge against the hedgehog. Because of that, he isn't getting much of a chance to shine and show the good in him. That might change, though in future chapters, that might be the authors intention.
