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

[Daralii]

I'm struggling to figure out which Garlean you're talking about here.
If you're talking about Nael Van Darmus, he was still well-established as a male in his original life, so their was nothing misleading about his name or voice provided in 1.0. His essence was merely placed into a female vessel at the Coils and they simply kept the same name. Probably thinking people would think of Nael as a seperate character if they swapped it.

I mean Nael's not that cut and dry. Moose had a good post talking about the ambiguity.
