The ONLY new race that has been added to FFXIV wasn't "cute". Male Au Ra looked feral and cool, and while female Au Ra could look cute with their petite frames, they can also look disturbing and monster-esque. It all depends on how you make them.

Besides, it's normal that the ONLY new race they've added so far would be more similar to the aesthetic of the races most people play. And by most people I mean both Japanese and Western players, who are equally as guilty of Roes and Highlanders being a minority. There's no mystery and no unfairness here.
