Don't worry, if we keep asking for it, they will add these waypoints. The same goes to Abyssea npcs, which were only available in Port Jeuno - then they implemented the changes. I totally agree with the OP, fast travel methods like in Adoulin should be implemented in ALL areas so you can travel from cities in the present (yes add Norg and Khazam) and to the past cities (including Walk of Echoes). Take a year off though, by the time you come back, it should be implemented
