This problem will persist until Ver2.0 when they are able to link the Market Wards of all 3 cities. Until that time everyone will continue to gravitate towards Ul'Dah as they have done in the past putting a strain on the curent servers that they are not equiped to handle. After Ver 2.0 and linkage players should start returning and using their home cities, at least til Ishgard <Jueno> opens up.
