anima needs to be only used for teleports! no trade ins, not seals, currency,etc. An idea thats not to hard for SE to make happen is allow poeple to buy lets call it Aetheryte shard or stone, you can thus use this at any Aetheryte Crystal or gate and teleport where ever u please and party members also that are in range just like normal anima warp.

Or maybe just make it so once you buy the aetheryte stone/shard you regen anima right then and their instead of using up inventory space and using it only at aetheryte crystals or gates like i just said. And SE could make a reasonable gil sink from this example maybe 1k-2k per item, and you're able to hold 99 in your inventory.

its good hamlet defense gives some anima reward, but this would help out just a bit more considering the slow regen of anima just over time.
