While I am not opposed to reducing - or even removing - the amount of teleportation done, a prerequisite for that must be that a large number of quests and questchains are changed/adjusted to drastically reduce the amount of back-and-forth required. Otherwise some parts would be just too painful. Especially the "Isn't this linkpearl nice. Now come back here so I can waste your time by telling you in person what I could just as well have told you in this conversation" moments.

And FYI - I use airships and chocobo porters as well as ferrys quite a bit. They are mostly cheaper than aetheryte travel, and reaches more places.
