My personal desires (for real and example purposes)

1- Enhanced Clothing/Hair Physics
I'm aware this would be difficult with current limitations, but I dream

2- Machinist Animation Adjustments
Specifically Gauss Barrel, both the attachment and the casting animations

3- Role Roulette for Duty Finder for players with multiple-able jobs
A fun way to randomize duties for players with a lot of different jobs, whether they have multiple jobs in the same role, or don't care which role they end up playing with any of their able jobs.

4- Surecast allows movement while casting
For BLM's and other affected jobs to gain some minor mobility options and add uses to Surecast, may have to increase cooldown
