WoW maps are not very cohierent (sp). I think ffxiv did a great job since the areas are pretty seemless. You also gotta understand alot was added in ffxi and WoW since their launches. ffxiv world is still pretty small we only have a few zones. think about 6 maybe 7 that I know of. 3 cities 3 areas out side of each city then the creepy area with the dragon corpse.
you have a forest, desert, cape plains. and a rocky terrain. Plus all the caves. and a few beaches
