Not a Viera expert either but

Seems to me the only time Vieras have ever been represented with their ears a bit higher than they look like was on FF Tactics Advance 2. The RDM's hat has ears that start on the hat rather than her skull. And that's just artwork.
Apart from that? Every Viera had normal ears.
I don't know where Yoshida and co. hallucinated these ears being higher as a standard, but they need to lay off the Gysahl Greens. It's getting in the way of their game-making abilities.
It's not just Viera and Hrothgar suffering. Name one patch that hasn't had something really stupid since Endwalker Early Access.
I think Square just wants to stealthily smother this game. Either that or see just how low we'll sink. How far we'll make up excuses for them.
