Viera can't use the new Modern Aesthetics - Modern Legend

[Nalien]

Yep, clearly have to look for it to see it xD

Now try noticing it from the front. Try examining them and immediately noticing the clipping without rotating their character. Try noticing that kind of clipping on the OF avatars, or their Lodestone page.

Meanwhile, Vieras ears sit on the top of their head, any clipping there is going to be noticed regardless of what angle you look at them from. It's simply a far more noticeable and egregious form of clipping, and I suspect SE wants to handle it better as a result, hence the extra work and time going into sorting it out.

EDIT: Let me put it this way, would you rather they rush out some options and you have just a bunch of clipping issues, or would you rather they take their time and not have those clipping issues? Imagine your examples there and slap them flat on the top of your characters head. Do you want clipping of that level or do you want them to mitigate that sort of disaster?
