They need to design something ala sea/sky so we can have things to do.
I'm just going to point out that Sky was released in Rise of Zilart expansion. Sea was released in Chains of Promathia expansion.

Yes, when FFXI Came to NA, RoZ was included. Presumably however, NA wanted to get the game at the same time as JP. Yay we have it! not as much content is in the game as when they would release a first expansion. Really, tough Beans.

Also, FFXI was modelled off of EQ (The most successful MMO at the time)
FFXIV: ARR is modelled off of WoW (The most successful MMO at the time)

The type of content is very different. That's a different discussion however, which has been beat to death.
