Great topic! I mostly lurk, but for this I want to make an exception.
My FFXI character is a mithra, but the long years in addition to the most common hairstyle made me grow tired of them. During the Abyssea era I created a taru alt for dualboxing...
...Which made the choice for XIV much easier. I first planned on playing as hyur, but then I remembered my taru. So, I ended up with a lala based on the looks of my taru. Apart from many different hairstyles and colours, she has mostly gone through subtle changes.
Last summer I made a "big" change: switching to plainsfolk. Later on I decided to change back to her original eye colour, and that's the current look.
Undoubtedly I'll make more small changes (and maybe change name to one that's true to the lore,) but for SB I'm sticking to lala. I've considered trying other races, but so far nothing else has felt right.
