Surprised they didn't combine spell/skill speed

With the removal of acc and parry I'm surprised they didn't also combine spell and skill speed into just speed.

Jobs are generally pigeonholed into using spells or skills anyway and on the jobs like PLD and DRK that use spells it's just annoying that you don't have access to spell speed. And it's not like the stats actually do anything different other than one is for physical and the other for magical. They both decrease cast and recast and increase DoT damage.

So why don't they just combine them into one speed stat like the attack speed stat?

This will probably happen at one point or another, but for now, it's as it is.
