XIV really needs to overhaul their sub-stat system. It's not broken as it is, but not even having a viable flexiblity in how you can customize, via materia, it's almost pointless to even exist as an option.

I'd propose the following changes ideas for sub-stats

Left side of gear and weapons would have/meld only offensive stats
- Crit
- Determination
- Versatility: A new stat that changes depending on your job. For some it increases proc rates, others may increase over-time effects, dance partner's damage bonus, etc.
- Speed: Merge both SkS and SpS. If we ever see a world not as bound by a 2min meta, this could be interesting for more jobs, or even making Speed potentially affect cooldowns too.

Right side of gear, accessories, would have only innate VIT, and more sockets than we have today, to freely customize uility stats
- Tenacity: Repurposed to be used by all, it reduces damage taken and increase the potency of defensive actions like Shadow Wall, Heart of Stone, Manaward, Radiant Aegis, etc
- Vigor: Increases the duration and reduces the recast time of Sprint and job specific movement actions
- Resilience: Reduces the duration of Brink of Death, Vulnerability and Damage Down status effects
- Spirit: Adds MP regen for healers and potency increase from some no-healer utility healing actions like Second Wind, Curing Waltz, etc

The idea behind the utility stats is that you freely customize them based on your play needs, not your dps goals. For example, a blind prog player may prefer more Resilience, given that they would probably be dying more often. A more experienced one could stack more Tenacity to ease the healing checks. We would probably need some capacity of healer rework to put all the utility provided by other jobs to good use even after prog.
