Personally if I were directing the game I would

1. Get rid of Anima
2. Implement new forms of transportation
a.Chocobos
b.Airships
c. Teleportation from High level Mage class which goes to 3 main cities aetheryte only
d. Implement an NPC in each town and camp which would serve similar to an outpost warp, and you could ask them to warp you to different camps every other in-game day for a price of 5,000 gil if in same zone and 10,000 gil if in another zone.
3. Change it so when you click on an aetheryte you have to confirm that you would like to set it as a home point
4. Implement items like Warp Cudgel from FFXI that will teleport you only to your home point
