I think Ishgard will be a 'normal' city but with some exceptions compared to the other cities, maybe. I was thinking that it could not have a levequest counter but only sidequests and special ones. A city that could be attacked by dragons sometimes (because its high position and its preliminay story) and you'll have to counterattack them. Maybe also some sort of missions given to you by a new order resident in the city. In any case, i really don't think it'll be a quiet city..
