Bring back Thaumaturge Spells!
I was responding to a Dark Knight thread and it had be reminiscing about the old-school Thaumaturge and how different it was from its current incarnation. I really would like to see a class/job that had those skills again. It balanced Umbral/Astral as Dark/Light, and had some serious buffs and debuffs. It got such a seriously wierd overhaul once it became the base class for Black Mage and SE removed all of it's unique abilities. I think Dark Knight would be a good fit, but either way I think it's something that ARR is lacking.
Spell exhibition I found:

Sidenote - I forgot the absurd amount of skills/spells that Conjurer used to have. It was basically Black Mage and White Mage all by itself. It's right before THM in the video.
Also, memories of 1.0 music :-)
