Perhaps surprisingly, I've never met my exact match. When I first joined in 2.x, my hairstyle was ridiculously popular so lots of other male Miqo'te had it, but everyone else usually seems to have a different hair color, skin tone, facial features, or eye color.I think most of the ones I see with the same face type and haircut have the beard and/or smaller eyes than I do. It also seems like my voice choice isn't very popular, I've encountered exactly two people using it in two years, both in DF-queued content.
While I generally don't see players who look like my FC mates either, there have been several NPCs who look like they could be the sisters of one of my officers, before she changed her hairstyle.
