Gender locked race?

[Alleo]

As I said in an earlier post-

Just because there are cracks in the vase, it does not mean you need to pick up a hammer and bash it more.

But having male Vieras would not have bashed it. They do exist. (Otherwise Vieras could not reproduce) The WoL is also someone with no defined past. Who is to say that a male Viera WoL did not just receive visions and decided that it would be better to the forest if he helps Eorzea? Or maybe he is just a Viera that never felt to be part of the forest and simply left. I mean the WoL being a male Viera would not mean that we suddenly have Viera NPCs everywhere.

Well, it actually is, even if people don't like it, it's still an unique 'trait' to the race.

Then why not just write it that no males exist because the reproduce different from us? Why tell us that males do exist but then dont give it to us?
