For a properly digitigrade humanoid, the body can still be balanced, it just changes where that balance lies.
For the example figures viewed side-on, the central "line of balance" sits over the middle of the foot.
Again experimenting with going into the pose myself, digitigrade stance shifts that line forwards - I think so it's over the front part of the foot that's still touching the ground. You don't stay standing straight - it's a slight crouch with knees bent to shift the rest of your body weight into a balanced position.
And I don't think the in-game Viera are doing that. They're shaped like a human wearing high heels and still standing upright, not in the actual stance that should be necessary for it to be practical. "Form over function" - it really looks like the worst thing to be wearing as a jungle warrior.
The concept-art males seem better - they've got more of the forward-shifted stance to balance properly on the front part of their feet.
I agree. It seems strange to me that Au Ra in general, and most of the few prominent female characters (Yugiri, Sadu, job quest characters) are strong, capable warrior types - and yet, even moreso than their physical design, their animations are very "cutesy" and seem designed to suit players being social with their cute dragon girl, rather than the race's actual lore. I can understand why they want it that way, but it still seems disappointing from a storytelling approach. I suspect it might also be frustrating for the script writers who need to set character emotes, because it would make it more difficult to find ones that suit the NPC's personality.
The more I think on it, the more it seems like Au Ra 'absorbed' parts of the Viera concept from when they were both being brainstormed together (and Au Ra won), and now Viera are being introduced.... still with that same lore concept. Fierce tribal warriors, dainty-looking women, powerful men - whether we get to see them or not.
And from a design standpoint, my hypothetical male Viera would probably end up in a similar space to the Au Ra I made... except I was trying to make him look un-fierce, and I'd probably be trying to go the opposite direction with the Viera. I wonder where they'd overlap...?
I could see that looking really impressive!
I think there's definitely good potential to have one face design that is a bit 'softer' if not specifically feminine, especially once you play around with customisation. Au Ra are similar.
The OP didn't mention Mithra at all. I searched the topic to check. They were only brought up in Enkidoh's post explaining why FFXI got gender-locked races in the first place. (Technical limitations, basically - to fit "two races in the space of one" so they could have more races overall. I do suspect FFXIV is heading towards similar limitations - I think the actual programming limit would be eight races - which might be an actual reason for getting a split race if they're doing that. Leaving one slot for a final extra race sometime in the future.)
And even so, it's still a very long jump from "I want this male counterpart to the female Viera" to interpreting that as saying "females really aren't worth having in game if there are no males", as you put it.
You can appreciate a character/race and their place in the game without wanting to play as them. I have no interest in playing as several of the existing races, but that doesn't mean they don't have value. They're just not for me. But they're still characters in the story and lore, I have no problem with them existing, and that's entirely disconnected from whether I'd want to play as the race or not.
The other thing with Viera is that even if we did have playable male and female characters, the established lore for NPCs would make it clear that we can't expect to see males as NPCs even if we can play as them. Female Viera would still stand alone as strong warriors who don't associate with males beyond the occasional mating.
I feel like it's better to not block people unless they're posting something really horrendous - and for that matter not assume "troll" unless someone is long-term disruptive. I feel like it's better to be aware of everything that's being said in a conversation.
