Twilight Sparkle is now a Alicorn Princess?

I just saw the Season 3 finale of My Little Pony: Friendship is Magic. And I have to say that I didn't like it, at best.One, I just wished that Twilight was turned into a Princess at the series finale( Not now, there's going to be a Season 4 and rumors of a season 5), it would have been more suitable. Two, now that Twilight is a Princess, what does everyone think things would turn out if she stays in Ponyville; especially now that she will have to perform royal duties much more often? Three, there's one less unicorn in the Mane Six, there's an unbalance amongst the pony races with Rarity as the only unicorn now. Four, even Lauren Faust disagreed with Twilight Sparkle becoming a Princess Alicorn like having Cadence into one instead of a regular unicorn on Tumblr/Twitter. So don't give me any crap of how it was destined to be of Twilight being in-between of Celestia and Luna as day and night and her Element of Harmony being a crown instead of the standard necklace. Five, you expect me to be happy that coronation episode was only made to sell an expensive toy?! Call me shallow, stuck-up, and even unreasonable, but I'm not liking how this is turning out to be. And I have every right to complain!
