That's right.. plastic surgeons!
Well, not really
What I do foresee is that when chapter 2 is released, there will probably be new hairstyles and faces added to the character creation templates, so.. short of rerolling a PvE character, perhaps it is possible to give chapter 1 account holders a grand total of one customisation when they bring their characters over?
I for one might probably find the notion of an asiatic elementalist intriguing "Heeyah! Taste my kong pow fireball!" and if additional visual styles are indeed available, it'd be best if we can switch over!
