Because some black people play this game too. It'd be nice to have a character to represent yourself that looks alittle closer to you.
I've only ever known four black people that played FFXI. One was my old roleplaying LS leader, and he was an Elvaan. Two were Mithras. Tummie plays a Tarutaru.
In my opinion, a more appropriate question would be, "If there is the option to change your skin tone in FFXIV, would you?"
I plan to play a Galka, or the closest thing to it if that's not what they actually call it. If there's an option to change its skin/fur color, I will probably lean towards looking like this
