For that matter, perhaps some 1.0 players could chime-in here, and delve a bit more into how the Classes were different back then? The Thaumaturge, for example, I'm told was more about the whole "Astral and Umbral" themes, whereas Black Mage is a much more traditional Elemental-Caster, which is true, could at least wind up being thematically more unique, perhaps having Astral spells do more damage during the Day (server-time), sort of reversing your rotation depending on the time of day.

Like I said, they may not be "classic Final Fantasy jobs", but I think the base Classes are still plenty interesting in their own right. I'd like to see them played-up a bit more, instead of just falling by the wayside.
