Keep anima but remove the ability to teleport anywhere. I'd rather just be able to use the main crystal in each city to travel to each camp much like we already can with the aetheryte gates. I think the recharge rate of anima is decent enough though I wouldn't mind a gil-sink recharge option for those who tend to overuse it, or really need it when they have very little left. One idea could be the ability to change dark matter into a certain amount of anima based on tier much like the materia conversion process.
