Everyone that had played the game until this day know the Eorzean world is not that "Final Fantasy" world that the non-mmo gamer expect from the franchise. My suggestion is very simple, make the 2.0 version of the world one unique, one amazing world full of incredibly beautiful views that the player can simply enjoy while doing his quest's, leves, etc. New mmo's are coming out this year FFXIV not only have the challenge of rebuilding itself, also it has to be a new game capable of going head to head with any of those new games. I found that the world needs more color, more "Fantasy", it needs new ways of moving around the world I don't mean mounts, here are some links just to give let you see what I mean.

high lands like this link, think of a place in which the player can see something as amazing.

A new area in Ul'dah like this link.

I believe in the game and in the team that is working hard to rebuild it. This videos are not my own they are just linked to offer a perspective of what I'm talking about.

From Ul'dah to grid? link ^^
