Suggestion for ex-pack: sea travel.

Pretty much this

It was stated That they had both Sky and Sea themes planned for expansions but they just chose to go with the Sky theme first.

Edit, misread some stuff.

i think of we got a sea focused expansion, they'd have to come up with a contrivance to block the established AirShip travel in those areas. Otherwise the whole feeling of setting sail and exploring the uncharted ocean kinda falls apart when you realize that people can simply fly around up there and ignore anything happening below.

Well, the only thing under the sea is Fishback territory.
What are we gonna do under there?For general exploration, It'd be great .. But again, the only thing under there is Sahagin stuff. An we're not exactly on friendly terms with them.

Not quite so true if you did the Sahagin dailies. They also told us there is a big sahagin city down there where the queen lives. I'd love to see her.

I just can't see an expansion being done where we get friendly with a Beastman Tribe.
The Daily Quests are pretty cool as a side thing. Something that is happening within the world, but an event that does not apply to the 'commonfolk / inhabitants' of Eorzea. The one they trust is the one adventurer with whom they worked directly with.

If we did get an expansion based at sea, i doubt very much that an underwater aspect would get any kind of real focus. Maybe the initial MS plotline is Limsa Lominsa going all out and obliterating the hostile Sahagins, then using the now free oceans to expand could work.
There is a lot of space within the world for all sorts of lands to come about. I'm not opposed to taking to the oceans to find them, i just don't expect much in the way of content ON that ocean. Theres not really much they COULD do with the ocean, outside of Pirates and Naval Combat involving said pirates. But it'd suck if we all we got out of a whole expansion was a gimmicky Naval Combat system that is toyed with once and then left alone by the players because all the real content is based on land.
