What is the purpose of letting us take Airships when you can just teleport everywhere? It's like...a very lazy way of trying to bring life into the lifeless Eorzea.
Because not all of us can afford to pay 500+ gil a pop, or want to sit and wait 1-5 minutes while riding the chocobus (To be fair, it's been a long time since I've ever rode an airship, but, it's there). Crazy, I know. But, we're out there.
