Keep anima, but seriously hurry up with the chocos and airships. If they would've had this at first, hardcore players would have felt less inclined the entire game to burn through all their anima in a week. They would've conserved a lot more, which is what will happen when they introduce chocos and ships.

The current system is bifurcated, you're either casual and burn as much anima as you gain, or you're hardcore and eventually have to walk everywhere. Nothing in between. The whole game's basically like that.
