What? There really isn't much canon information on alicorns in general, mainly just the specifics regarding Cadence, Luna, and Celestia. We really don't have the full info and context regarding Twilight's new abilities.
Lauren Faust said little girls are more complex to be impressed by girly cliches. Megan McCarthy said that-every girl wants to be a Princess. Really? Must I even elaborate?And please if you are all gonna bitch back dont block first.
I'm just saying we don't know all the details yet, so it seems a bit early to lay the blame entirely on Twilight. My comment was about your statement that Twilight was reducing alicorns to genetic mistakes. It seems more likely to me that she will get her powers through a spell mix-up.
