Being able to have our own ship will be awesome, specially if, instead of spending tremendous amounts of gil, they make it like "you can have it IF you can build one" They giving a monstruous list of materials and, once you get them all (including some exclusive stuff...i'd hate to see people, instead of buying a ship just buying all parts...would be a shame since would have no merit in this) you receive your ship.
I would love it they implemented this!!!! It would encourage all the DOL and DOH to work together and then DOW/DOM can farm the shards/crystals required, meaning not matter what class you are you will be able to have an input.
