(Maybe) lessening the stigma of leaving the village / forest and explaining what male Viera do with their lives isn't particularly significant.
They're still the exact same people from the exact same locale in the exact same region they are in Ivalice, with the exact same social structure and the exact same clans and the exact same attitude toward outsiders. They are the exact same people from Ivalice - just like people wanted. If that leads to the males being unplayable, well... careful what'cha wish for, I guess.
I still don't think that's the case, but whatevs...
