I really don't get why some people don't like the of Twilight being an alicorn. I mean, it's understandable that Celestia and Luna are basically the physical form of GODS, and that having so many alicorns would just be overkill! But then again, we wouldn't have been able to have a scene as epic as the fight scene between Twilight and Tirek (what I think is the pinnacle of the show's animation)
