What classes/jobs would an average Garlean be capable of performing? [spoilers]

[NegativeS]

Hark, children, and lend thine ears unto a post of middling purpose and extensive subjectivity, whose existence only serves to clog the forum and sate mine own curiosity on a topic none asked about.

It has been stated that most Garleans are wholly unable to manipulate aether, for reasons. This is likely the main reason why we haven't had them playable, as most jobs either explicitly or implicatively manipulate aether in the majority of their actions.

The thing is, 'manipulating aether' isn't super well defined in this context. All living things are made of 'usable' aether (or dynamis, but I think I can safely assume there aren't any Meteions walking around Garlemald), but is manipulating it or environmental aether an active or a passive process? Would absorbing aether from food be considered manipulating it? What about wielding another being's aether in the case of the Reaper?

Because it's a Sunday morning and I'm dead-bored of levelling jobs, I figured it might be a fun thought excersize to go through all the jobs and try to reason whether or not a Garlean would be able to perform them in any meaningful capacity.

Note that this is for pure-blooded Garleans and not just any member of the (now-defunct) empire, as the empire was known to conscript those of other races from conquered territories who could manipulate aether (and have been showcased doing so many times).

Feel free to let me know if you disagree with any of these.

Tier 0: Entirely Incapable
Jobs in this tier are entirely based around manipulating environmental aether, and no pure-blooded Garlean would be capable of performing them in any capacity reminiscent of the real job. Kind of obviously, this includes most DoM jobs.

• Dark Knight

A standout in this tier, a Dark Knight's abilities from the very start seem to harness their weird umbral power to enhance their strikes, visible even in the Lv. 1 skill Hard Slash. Perhaps if every Garlean had a Fray to evoke their deepest emotions, they might be able to squeeze something out subconsciously, but an average Garlean picking up a greatsword would probably be closer to a neutered Warrior than anything else.

• Astrologian
• Black Mage
• Blue Mage
• Pictomancer
• Summoner
• White Mage

For obvious reasons.
