I'm feeling a lot better now…had a good rest, and got some advice…
Thank you all for being buddies
Alicorns, you say?
Well, I do think about that, Zero
For one, I think King Sombra pretty much eliminated the need that an alicorn was the de facto equine leader. He proved that even a unicorn was able to rule a kingdom (and according to Celestia, a really powerful/necessary one too).
Another thing I liked to re-point-out is Chrysalis and her changelings…
…all have wings and a horn. I know, different race, but still an equine one. That's what we're looking at. Equines , not necessarily ponies (in fact, we see four different equine groups in the series so far: regular ponies, crystal ponies, zebras, and changelings). This practically proves alicorn-like species can be subservient too.
So what are alicorns?
One theory I put forth is that its simply a genetic mutation. The fact you have wings and a horn is peculiar, but you're not exactly a god. The reason why Celestia and Luna are the way they are is because they overthrew Discord and inherited some sort of power that made them immortal leaders of the land.
A bit like the Mandate of Heaven in China. The rulers are the sole rulers and hold all the powers of one (in this case, it includes immortality in Equestria) until such a time when they are unworthy of the position and are overthrown by the next rightful ruler(s) (Discord beaten by Celestia + Luna), and these new ones inherit the same mandate.
This also explains Cadence, being a powerful, but not exactly to par with her aunts, being. Hell, Shining Armor was able to generate a shield that defended all of Canterlot up to his wedding, Twilight has also shown abilities in shield making, so that rules out its "an alicorn thing".
Another theory that can be used in conjunction or replace it is that the alicorns (or just Celestia and Luna's family) are a bloodline. Like the Targaryens of A Song of Ice and Fire (Game of Thrones) or Mongols and Manchus to China. Foreign rulers who have held the position of ruler of a nation for a long period of time, a sort of dynasty.
However, that mention of Cadence (being denoted to love and all) does mean that there's possibly something to being an alicorn. However, he specialty may just be a result of her special talent for which she got her cutie mark, rather than a god-like attribute
So in short; being an alicorn doesn't exactly make you a god. But you're pretty special nonethelss
