How about.... we set anima to a max of 50, and you can only teleport between Aetheryte Crystals and Aetheryeal Gates in the same region?

So instead of teleporting from anywhere, you have to physically go to the Ul'dah Aetheryte, then select a destination somewhere in Thanalan, and that expends one anima.

If you want to travel to a camp or gate somewhere in La Noscea, guess what? Take the airship or ferry to Limsa and use it's Aetheryte.
