I see a lot of people speculating based on the woman in the trailer, discussing if she is a DNC or a MNK. That woman obvipusly isn't Uda, she doesn't have the tattoos in her neck, which wasn't forgotten by SE because in ARR opening you see her tattoo.

Sooooo that's certain to be here sister. Being her sister, an Ala Mhigan and being parte of the resistance, she probably was trained with martial arts like Yda, but why couldn't she develop a love and interest in Dancing, mixing martial arts (offensive stance) with dancing moves/posture (buff/debuff/healing stance)?

So I'm hoping, and want só bad, SE is bringing DNC. Come to papa!
