I see no reason to change anima, I usually hover between 6-12 anima anyways. If you play the game alot you will find that the 100 anima you start with is no where near enough, especially if you are a crafter.

So I have a feeling chocos and airships will be used highly even with the current system. In 1 leve day I can blow around 6-10 anima depending on where my and my group goes. And that does not even include crafting and gathering stuff which are done in different zones. 12-15 anima a day for a full time player is what is about average, that is not enough to use reliably past 2 weeks of game time.

Anima is for the casual ppl playing 8-10hrs a week, a gamer would need almost double the anima before airships and chocos become worthless.
