Just an idea for the distant future, but it would be great to have ambushes on ferries and airships - sort of like what you see in the intro for Limsa Lominsa. I'm thinking the mobs would have to be passive, because it would be a poor shame if anyone died on the trip there. They could just be level 10-15 mobs, just something to give new players something to gawk at on their first few ferry trips, since most higher leveled players use anima and chocobos to travel.
