You do understand, that by adding the "option" to ride the airship you are forcing the development teams hand to make all Airship based content yet again more instances right?

There will be no random battles and there will be no random NMs because you will have to plan on bringing a party on board the airship just to get enough people on it to participate. In fact it will probably become a completely guaranteed encounter. No more chance of a casual ride.

Yay for 100% instanced Final Fantasy
