...wait, I never said anything about Alphinaud other than using his age as a benchmark for Elezen aging. He's more or less the only character of the race (discounting his twin for fairly obvious reasons) who has a concrete age given, and it's one that's very illustrative of the point that Fernhalwes made at Fanfest about Elezen aging. At 16, he looks like a child in a way that cannot be replicated with the character generation tools we have. Whereas a 16-year-old Lalafell or Miqo'te or Midlander would be a completely plausible character to make as a player character, a 16-year-old Elezen would be impossible- and we don't know how old even the youngest-looking Elezen we could make would have to be in order to make any sense.
