I'd like to see the role of anima scaled back somewhat, so that it's mostly just used for very long-distance travel.
Then add a variety of buffs/consumables to enhance foot travel.
Plus the addition of a variety of 'mounted' travel options, including things for mid-range travel. For example a Ferry or Carriage which could be faster than foot travel and automatic (and thus, safe), or a mount like a Chocobo which is faster still but manually controlled (and therefore without a fixed path/destination).
