What does intellect and mind represent anyway?

The TTRPGs I GMed usually had knowledge as feats that carry situational statistical buffs, and INT was more of a character's ability to reason, solve problems and so on, so forth (there was no WIS).

For some reason, I associated cognitive speed with spell speed in a FF14 context.

Nowdays there's no difference gameplay wise. They might as well trim out both stats and replace them with MP - Magical Potency.

And then you would have one set of gear for both healing and caster DPS, rather than two.
