I don't want viera male/ hrothgar female because I know it will be botched just like the current viera & hrothgar are- I'd put all my cards to fixing those two races 1st

Graphics & engine upgrade
Give Viera & Hrothgar hats- Matoya's Hat made visible, give Viera Y'sthola's hairstyle from mog station
Long hairstyles (like Gaia's & Rynes)
Hilda's Ponytail
Updated & improved character creator
For devs to take inspiration from the best ffxiv character mods- which are literally long hairstyles/ curly hairstyles, braids, & skin textures.

More make-up choices -
