I have never actually managed to work out a satisfactory backstory for those two - especially after canon trampled what I did have.

Following up on that, Celestia and Luna were both born in the Crystal Empire and lived there until a few years before Discord came through for the first time, and their motivation to help it stems from that rather than any magical importance.
 
In addition, there’s no biological difference between Crystal ponies and earth ponies - their slightly different appearances are a effect of the magic of the Crystal Heart. away from it, they’ll look like any regular earth pony.

Grogar’s regime is the reason why all races and nations outside Equestria still think that Equestria is a land infested with monsters, which is best avoided.

Wasn’t there a scene where the Mane Six somehow got themselves crystallized?

I suppose it’s also possible that long-term exposure makes it so that the crystal skin lasts a while after one leaves the heart’s area of effect.
 
Also: Tempest never got a cutie mark because she was going to get one in magic, but then her horn got knocked off.

Well if it’s truly destiny, you won’t be. And if it’s more flexible, then your talent will adapt.
 
(In my headcanon, the only adult blank flanks have been in persistent vegatative states since they were still young enough to be marked. And I’m not even sure about them.)

A Changeling who consumes too much love can become fat.
 
Changeling mind-control magic is based on love. If no one loves you, you’re immune. This doesn’t mean Queen Chrysalis can’t telekinetically drop a house-sized boulder on you, of course.

Changeling bodies run very hot for their size.
 
They become quite mindless and frenzied if put in higher heat for too long, and sluggish in cold climates.
 
Despite this, they can withstand below freezing temperatures, and harsh glacial environments are seen as ‘vacation spots’ for them.

Wouldn’t it be more important that you not love anyone else?

The Dazzlings are redeemed by the end of Rainbow Rocks, and it later confirmed as evidenced in Backstage Pass, seen when they remind Sunset they’re not causing the time loop and claiming they “paid the price” for “manipulating” Canterlot High

Depends on the punchline you’re going for. This one is pulled from a 4chan second-person greentext in which Anon is the only one who can stop Chrysalis, because no one loves him. No one’s grateful to him afterwards for saving the day, either. Being Anon is suffering.

Cadence is the princess of love but she’s really only the princess of romance (eros) and family (storge). Twilight is the princess of friendship (philia) and unconditional love, i.e. putting others well-being before oneself (agape).
