I'm not a fan of the current system, but until airships and choco's are introduced we don't have much of a choice. For airships to be viable the current teleport system would have to be edited and the cities removed from the lists. As long as they are still on the anima list people would rarely use the airships.

Also, I would like the current system to be changed to port you to an outpost that is not right directly at the camp. Finally, give us chocobo already! Chocobo are a staple of a FF game and it does not feel right without them as a means of transportation.
