The director has made the decision not to do this. The male Miqo'te markings are a special characteristic of the race, and aren't actually tattoos. They are born with these markings and they become deeper in color as they grow older, but similar to people who have thin and thick facial hair, there are individual differences. With that said, there are some female Miqo'te face types that do not have this, but all of the male face types do. This is something the development team wants to adhere to and we appreciate your understanding.
Also, current face types/facial hair options are what they'll be at launch. After launch, they say they'll weigh whether or not to prioritize new faces for existing races, or new races, period (I hope the former). But they don't immediately intend to launch new ones. I guess the idea is that they were balancing memory usage against customization - the fewer individual options a machine has to load, the less juice it takes. Part of their goal for ARR was to expand their range of tech support, so this could be a casualty of that.
They'll be adding new hair options after launch, as well as a salon-esque system to allow you to change them. They are withholding comment on whether or not you'll be able to change your face (and I assume that decision won't be decided until new faces exist).
