Maybe they should make it so that people can own and build their own Airships, then we could have large PVP wars against other linkshell ships.
You would be able to board their ship and take them on directly if you get close enough the option would appear.
There would plenty of quests that require a large airship and linkshell for completion, imagine fighting Bahamut with your linkshells airship.
Crafters would to build airships, first you would need a blueprint and then you would need lots of high level parts that drop off of certain leves/NMs, crafters would also be able to repair the ship while still in mid-fight.
I think people should be allowed to own a single pilot ship or a small ship with a 1-3 passangers.
It would be nice if the sky was a new place to explore, with places you wouldn't normally be able to reach.
It would cool to see a merchant ship that's owned by a player with his or her retainer on the deck, so that people can stock up on resources without having to go back to town.
Being able to teleport to your linkshells airship would be a plus too, that way people would have no excuse for being late. :P
Maybe i'm just being a little bit too enthusiastic. lol
