Discrepancy in lore (spoilers)

[Jandor]

Our powers are substantial enough that we can, and we have dedicated mages and artillery for those occasions.

Shouldn't need a lot of explanation when there's literally cutscenes of the Xaela's flying on birds and down airships with axes and magic.

A cutscene of Hien riding a Yol cutting a sky armor out of the sky with one stroke of his katana.

Powerful groups of dedicated anti-air mages backed by artillery? That sounds cool, would have been nice to ever see that.

The Xaela tribes aren't deployed in Eorzea, and they don't fight any airships. They fight a force that as far as we can see consists entirely of the much much smaller Juggernauts, those things aren't that much bigger than a Yol.

Funny you mention that Hien cutscene too, that would be the cutscene where Eorzea is yet again failing when up against Garlean air power, and yet again have to be bailed out by someone else?

Seriously, what sort of absolute morons don't expect to face aerial units when sieging a city held by a faction known for air power? What an absolute clown show of a military campaign.
