SE is slowly adjusting FFXIV to the mood of modern eras but the vocal playerbase makes it hard to do because whatever they attempt to add it's often followed by a backlash.
Eureka is a good example...
(the bunny outfit thingy irks me a little. All I see is that the gender equality was just a pretext to get this particular outfit, but that's just me).
Yoshi is unconfortable with male Viera, they are apaprently not "bara" enough to him. Which is from what I've heard the reason he doesn't want to include them and instead create a whole new race he can model as he wishes.
People see FF has a (gosh this sounds so weird but) genderfluid brand. So they assume that FFXIV must follow this trend. Legit.
Yet Yoshi doesn't have to.
FFXIV is not some Visual Kei/Malice Mizer themed fun park from what I know, not all NPC wear loli dresses nor makeup.
Also..
Viera are females.
The lore acknowledge a few males, sure, but in the end they have always been females in most people's mind.
I don't understand why it's such a shock they apppear to be genderlocked.
The Vieras are part of the FFXII, Final Fantasy XII: Revenant Wings, Final Fantasy Tactics Advance, Final Fantasy Tactics A2: Grimoire of the Rift..
In all theses games they have always been female only (the male being absents or non depicted).
The Races from FFXIV were created for MMOs (based on FF11 ones). They don't appear in other FF so them being tempered with is no real biggie I suppose.
Vieras are imported from an other video game, sure their lore may have been altered but still
They went with the exact FF12 design and if back then they didn't include the males so there are no obvious reasons that'd force SE to do it now.
If they had their own version of the Viera it would appear to me more illogic not having males.
I know, male Vieras in FF12 don't have any official design but that's because they didn't want them to take part in the story (I guess?)
I'm not fan of gender locked races but I do understand the logic behind it.
(Sorry I sound like an asshole).
