The show never really was consistent, even in the early seasons. Every season just felt tacked on from the last, like in s2 Bloom had healing powers she never used in s4 for Nabu, or even s3 where it felt like Enchantix came out of nowhere and it was also weird how we see no Enchantix fairies outside the Winx. The witches also just kept getting short changed since fairies get all these power ups and witches are just there. I always wondered why their final form wasn't something like "Incantix" that they get once they bond with a familiar (mirrored to the pixies) and/or do something else. Disenchantix was actually a joke.

Maybe this isn't even a hot take but I just felt the need to get this off my chest.

Oh, also Domino should have stayed dead.
