I agree with this compeletly ... Though I see it alittle differently, think of pound and pumpkin cake, in that Ep a few seasons back bronies either liked or hated them, liked them for there cuteness, hated them for either how badly they were made or because they could fly and use magic so young ... Or both, don't matter to me ... Now mix the two of them and make it look like the Flurry Heart we have today and u have all the reasons as to why I hate her
As far as the other Princess's go, while Twi and most likely Cadence had to earn the right to be a Princess, that doesn't mean Celestia and Luna had to ... From what we know they (apart from Flurry Heart ofc) must of been naturally born alicorns, but in the premier, Celestia said something that doesn't add up with all the headcanon I have up to this point "I don't know, this is the first ever alicorn to be born naturally" or something like that ... This just raises more questions about Celestia that I personally wanna know .... Anyways back on topic ....
While yes I do like the colour scheme of Flurry Heart, that's about it, Hasbro started copying Bronies for once ... They made a canon OP Alicorn ... Fun level percentage = 0%
