...While I don't necessarily agree with Nethereal re: Elezen attractiveness, it is important to note that most players aren't choosing their race based on lore or RP purposes, but on aesthetics, as she is implying. Catgirls tend to be considered attractive by a lot of people (personally and culturally), and for players who really don't care about immersion or just want to look good, they'll pick female Miqo'te. Same tends to go for female Au Ra characters (I say this fully acknowledging my main is one of them). A lot of people also prefer to play as the nearest equivalent to humans in fantasy or sci-fi games, for whatever reason, so they're more widely chosen (not to mention all the gil-farming bots that just pick the default options during character creation...). Elezen, by proxy, tend to be chosen less as a result, though I think they're still generally more popular than Roegadyn.
