I'm glad the DevTeam has a pretty good track record in seeing through suggestions that are based in hampering the conveniences they're attempting to offer in the first place - or this would be worrysome.
Consider me in the camp of people who think that the side-effect of this idea being the increased difficulty of getting a group together in a timely fashion make it not worth the change.
I honestly think that when Chocobos and Airships come out, people will actually be more reluctant to spend their "get anywhere in a pinch, just in case" points -- at least put this request off until they've been instated for a little while - otherwise these claims are base speculation with no empirical evidence other than the fact people are careless with their anima at present - which is more likely because of a lack of alternative options in the face of not wanting to walk unassisted by chocobos and airships than it is because they're just lazy, soiled, ungrateful casuals.
