Why doesnt TP Regen scale with Skill Speed?

[Sinaloa]

Skill Speed vs Spell speed isnt even arguable; BLM have an infinite amount of resources to utilize SpS efficiently, while physical DPS almost receive a hindrance for adding more SkS, is there a reason for this or is it oversight?

Physical classes do way more damage with their white hits which profit quite a lot from skill speed. A monk I know how claims to sit at 320+ dps told me 40% of his damage comes form autoattacking. Quite a good reason to invest in those. You just need to find the balance where more autoattacks do less damage than higher TP-Skills. No min-maxing here.
