These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Conversion Bureau: Conquer the Stars
Ensemble Darkhorse: Firebird rapidly became a fan favorite before the first chapter was even completed.
Discussed on the forums with regards to Firebird's parents (and Newfoals in general). ''Not Alone'' and this story firmly establish that the Newfoals are complete doormats who are unable to feel anger or be assertive. On the other hand, their children are born normal, with the full range of emotions. So it's not much of a stretch to believe that a good number of Newfoal parents, while they would be loving and caring, would be horrible disciplinarians and be way too overly indulgent, resulting in Spoiled Brats that would put Diamond Tiara to shame, or children with a heavy chip on their shoulder (like Firebird, whose special talent is being a Bully Hunter pretty much). On that note, what if a Newfoal that married a natural-born pony ended up getting abused or exploited due to their passiveness?
Imagine if Equestria had won the war. Literally billions of ponies would then be born to newfoal parents completely unprepared to care for them; it's not hard to imagine them dying en masse due to poor care.
If Celestia and Luna are not back on Gaia, are the Sun and Moon moving? If not, what happened to the rest of the world?
At least one discussion on the forum was confirmed that the Newfoals are so pacifistic, they would ask that their limbs be tied up so they don't accidentally kick someone... as they're being dragged away by a lynch mob.
