Big 'yes please' from me.
It's the #1 item on my customization wishlist for FFXIV closely followed by getting rid of gender locks on stuff.

If they added some actual beards to all the male options (or approriate equivalents in case of aura), I'd buy a fantasia in a heart beat.

don't really mind if some nice long braided beard might end up clipping into clothes, hair already does that half the time anyways.

Just give us something actually worthy of the term 'beard' not just some short fuzzy stuff not even reachign past a characters neck.
