Why are skill speed & spell speed separate stats?

[DefendPopPunk]

It might not be the reason why, but perhaps they had the same system in mind that they used in ffxi, where you had job traits like fast cast and job abilities that lowered weapon delay (and maybe in ffxiv's case, tp attacks' gcd), and then haste that would increase the speed both of those aspects at the same time. Maybe in the future we might get these types of things too, and a haste spell, that might make the separation make more sense.

[Kyroc]

because skills are restricted by the gcd, and spells are restricted by their cast time

Spell speed reduces both cast time and GCD

[Dano]

cast time and GCD are two different things

Probably because each stat has its own formula in the game codes and they don't want a single skill affecting two types of skills. They wouldn't want other classes casting stoneskin faster for example. That's my guess.

But every other secondary stat (save parry) already effects physical skills, spells and even auto attacks. Skill Speed/Spell Speed are the only stats that don't.

Tl;dr version of this:

"We don't want players to rely on spell Haste like they did in FFXI or other Final Fantasy games."

I think you have answered the question by mentioning Flash for example.
If flash is affected by Skill Speed, then you may cast it more frequently, apparently the system was designed to restrcit you to do that. ^^

Why would that be a bad thing? It's already worse in terms of threat generated and damage done (none) than the warrior's overpower. So it should also not be affected by the any "speed" gear that the PLD wears? That makes no sense.

Seems more like an oversight than actual intended design.

Uhhh ... what?

That was Yoshida's reasoning for this Skill/Spell system when Haste spell would simply solve all issues - He simply wanted to try to nip an issue before it crops up, but as proven with everything else he tried in that regard, it didn't help.

Perhaps to keep in mind for future content (perhaps NIN even, depending if Ninjutsu has a cast time) for melee/caster hybrids.
PLD is another example - since PLD doesn't have any spell speed gear (minus materia melds), it means that casting spells like Stoneskin will be at the default 2.5secs recast.
