Yeah, but this Viera was actually surprised* it was fell with one arrow. Though that seems like a want to just build up the fact this mViera killed multiple of those beasts with one arrow a shot, saved the girl and then was quick/fast enough and stealthy enough to escape the area as soon as he saw us. Which, given the fact WoL/WoD has god-like a sixth sense to hone in on people who are watching/looking at them - is impressive.
*Regarding that fViera - she was surprised it was fell with one arrow because she only knew of one type of person who could do such 'handy work' - a mViera. She thought they had all perished.
We - the WoL/WoD can't even take down those beasts with one hit.
The women are described as just as formidable, but the females also have a sporty/model like body. The males should be pretty/handsome by default. Otherwise, all fViera somehow take after their mothers. Which is weird for a race that is hellbent on having the men being the strongest of the strong in endurance and survivability. The women-only allows the 'master alpha males' to breed. That's not something I doubt they'll retcon giving the previous statement where they said that matsuno helped with that and they're not about to spin it to their own directive. Which is good really. Matsuno's idea of a mViera is likely to be the one we will get, if at all.

As for the comment regarding them changing it. Of course, they can, literally, the only thing that describes them is one supposed comment from a female Viera saying they're 'mad' and 'muscular' - which I'm hunting down to find. And of course the lore from FF14. Which doesn't have a descriptive in their physical appearance. Only their cold personality. They shoot to kill.
Anyway, we know they're there and we know they're having children. Since a pixie literally said they're scared of Vii children. Perhaps, just perhaps we might see one. Seeing as they seemed to have lessened their workload. Only one dungeon next patch, we will see. They're adding in a lot more lore going by the previous stream they had.
I'm unsure why people have such an aversion to them being fierce. The female Viera as they are now can be described as fierce.
