Regula van Hydrus (potential spoilers until the end of Heavensward)

[Arixtotle]

and again, its way of behaving (well, 1.x nael didn't gave it away either) but due to is dialogs and voice acting (ive heard it in game in both english and japanese the Aethereocmical...... facilty fight and sounds male to me.)

I'm sorry. I'm a bit confused. Are you saying Regula "acts male" and therefore is male? There's no such thing as acting male or female.

About the voice acting, that's personally why I'm so confused. All the voice acting is male and yet the name is female. I just can't imagine NO ONE noticing the discrepancy during development or Localization.
