Does it though? The actual lore in regards to male Viera makes leaving their traditional role more attractive than it would be for a female Viera, and female Viera also have the strict social taboo of "Don't leave the forest ever" but they're being given the "Some people rebel against their culture" reasoning. Sure there's also the 1/8 lore on the birth rate, but that's essentially the case with the catboys right?
I get the time constraints but the "respect the lore" argument is terrible, the lore isn't good enough to support it, it wasn't in ivalice either but ivalice was a single player game where the Viera had a specific role to fill in the story, the role of being a playable race for the main character of an MMO is way different and needs a far better lore reasoning if lore is a reason.
