Man, I really like your story, I agree with you about the amount of OC's, I think it was too much for a few chapters, as for the Griffins, I loved the concept at first, but you did everything very OP, it was hard to believe that the MC would have realistic difficulties when he had so much at his disposal regarding powers. I think the world of Harry Potter doesn't scale as much in terms of raw power as what was talked about, and even if it did, it was introduced very early on. Well, that's my opinion as a reader, I think it's a good opportunity for you to remake this story better thought out; and my congratulations on realizing what happened to the story, most would just give up or not care.
While do agree that it was too early or too soon for the MC to be a bit too OP not to mention more then one OCs I also gotta say that it also is what makes this book bit different from the ones based on what this one has that others don't i.e griffens and bonding with them via blood magic as well a vow of secrecy gaining abilities or other things and vice versa from the beast and way how to get the inheritance of the Everhart Family but also would be good to remake this book with the MC not being OP so early on the book while also maybe being the son of Flamel or Peverell since more options would be presented in the way of what path u would want the MC to follow as a OC now while being a Dumbledore would be good and would have OC connected to Albus himself as well in a way his plans and ideas including Harry Potter just would have to say either one of the other two in order to have more freedom and do things differently look forward to reading what u come up and do enjoy this book it's quite interesting and intriguing
