When Yoshi-P first brought up the Sea of Clouds content coming in Heavensward - paraphrasing:

"You will travel by FC Airship into the Sea of Clouds. However, if you come to an Island and the monsters are gone, it means another FC got there before you did."

Now we are being told that the FC airships and an airship landing at Ishgard will make it accessible to everyone.

Please provide us with explination on how the Sea of Clouds has evolved so that we aren't potentially looking for things that are now in the landfill of the creation room floor.
