From a writing angle, it's all backwards.
When other regions were created, the region came first- if even in concept- and that informed the characters. With Wuk, they created her first and then tried to build tje world around her.
That part's classical stage writing. What makes it sting though is in the pursuit of her having a positive, upbeat expac... they erased all teeth the story could have, made everyone around Wuk morons, and gave her wins and screen time where nothing was done.
I'm ambivalent on Stormblood, by the by. It was alright. Not amazing, not terrible either. It was clumsy, but there was an earnestness to a lot of it.
I don't know what in Jibbers Crabst name happened here.
