The problem is that we know that primals change their look depending on the summoners. So why should the current Ixals, who never really knew the old Garuda, summon her as that and not as an overgrown Ixal woman? Yet Titan and other male primals (Ramuh is the only one looking more human) are way more beastly.
Again out of the triad Sophia, the only female, is also the only one that is really human looking. I know that they did it as a homage yet it would still be nice to be more consistent with the primals and not always make the females the good looking ones and the males beastly.
In the end this is just for fanservice or as an homage and I find this a bit sad..why not change it a bit and make a good looking male primal and a really beastly lady? Or make them both look more like primals from their race. I mean Shiva is fine since she is the imagination of Ysayle and the old Shiva was a human. But I just cant believe that the Ananta or the Ixal would summon something so human looking. And look at Lakshimi from the waist up, she truly looks like a real human. While the faces of the Ananta dont look that human. So why would they summon their goddess in such a way?
