Lol I completed all of cataclysm. And as far as world change this game has about as many zones that cataclysm changed/introduced, if not less. The play style did change however little for most classes, healers mana, hunters focus etc. The class playstyle changes coming to FF14 will not be much more dramatic. I know this isn't cataclysm but it's a comparison that proves my point because although those changes were made to WoW, it didn't change the fact that it's WoW. Same will happen with FF14 and i do hope it's for the best. So come P2P ill leave, and come back with a trial for 2.0, if it's fun and worthwhile i may stay.
