I hate My Little Pony gen 5. I feel like y'all should know that. Cause I do. There's a lot I hate about it, but there are two things that I hate in particular. Number one is that they decided to give EARTH PONIES MAGIC!!! The second one was that they decided that FLIGHT disappeared with magic. Like.. huh?!
In my opinion, the earth ponies' lack of magic is pretty important to the tribal story. Unicorn magic was primarily used to raise and set the sun/moon (which had the high probability of draining sorcerers of all their magic forever), and pegasi took care of the weather. Earth ponies, without any particular special ability, tended to fields and grew food, which was used as payment for the unicorn and pegasi's work.
In my humble opinion, earth ponies were an example that you don't particularly need a special ability to be helpful or an essential asset. To give earth ponies magic is just.. plain dumb. I think it would have been more beneficial to have an episode with that very lesson: "You don't need a super special talent to be worth something."
To address the whole pegasus flight thing, IT PISSES ME OFF BECAUSE IT'S NOT A MAGICAL ABILITY (realistically impossible, sure, but not magical). And if anyone tries to defend them saying something about Tirek consuming flight, that only happened after he collected enough MAGIC. It was a whole other thing! After he gained strength from unicorn magic, he gained the ability to consume flight and strength. TWO. DIFFERENT. THINGS.
I might be dumb and shit, but yuh.
