Beta phase 2: Miqo'te(F) + Hyur(F)
Beta phase 3: Miqo'te(F) + Hyur(F) both to close to Lv.30
2.0: Miqo'te(F) Lv.50 + Hyur(F) Lv.50 + Hyur(M) Lv.50 + Lalafell(F) Lv.24 + Roegadyn(M) Lv.16
Now: Hyur(F) + Hyur(M)

In the end I deleted my Miqo'te because I absolutely hate how those ears deform the helms, looking especially stupid with tanking gear and cowls that are part of the chest piece and hence cannot be hidden. The tail is fine, as most gear either are designed specifically to look proper with a tail, or it just happens to look like an opening is there for the tail.

Obviously there are some odd ones like the reindeer outfit.

But that's only for gear. One thing I hate about the tail is how it is absolutely rigid when a Miqo'te is mounted. It doesn't move. It absolutely doesn't move. It looks 100% dead. It looks especially out of place on the unicorn. You don't notice it on the chocobo due to the saddle, but it's an eye-sore on the unicorn and other mounts that don't have elaborate saddles.

And I tried, oh I tried to get used to it. My Miqo'te(F) not only was a Lv.50 PLD + Lv.30 WHM, it also has all crafts and gathering classes at Lv.30, plus the remaining all battle classes at Lv.15. I still deleted it. (Well the real reason for deleting is I know I cannot invest the time required to maintain so many characters; but the reason for which one to delete was due to the ears and tail.)

I would suggest that you just create a new Miqo'te and try it out. It takes at most two weekends to get the Unicorn, if you play leisurely.
