We've loostened anima to the point where other transportation isn't really necessary any more. Like someone said, it's become a good outpost warping system, which I pretty much exclusively used in FFXI once I built them up. Maybe they should just ditch the idea of airships as transportation from place to place within this vanilla game and make them more important in subsequent expansions. Within this game, just expand on airship and chocobo lore and add content related to them that is novel. Airship-related quests. Airship-related synths. Chocobo events. Chocobo goal-directed content. But we honestly don't need straight transportation right now.
They shouldn't nerf anima once they add transportation. The game is in no state to be withdrawing features, as if we have enough gameplay choice here. It's up to them to design a point to using chocobos and airships if they are going to be this late to the game with them. Not to release them and say here here they are, we'll be taking that anima now thanks.
