There Is No Dancer (yet)

[Neophyte]

Watched the video again and it's more than clear that we seeing a Dancer with Martial Arts moves. Specially her intro.

This girl is as much as a "dancer" (i.e. the well known FF Job "dancer", which utilizes Dances for different status effects, also likely with their reccurring signature attack ability "Sword Dance/Blade Dance/Saber Dance/Quiver Sword") as any given gold Saucer NPC is a "gambler" (i.e. the well known FF job "gambler", which battle abilities consist of random effects that are extremely powerful when successful, but detrimental if unsuccessful and a recurring signature attack ability called "Slots").
