I'd like to see them do something with the GC for each area with regards to transportation. I always though it would be a neat idea to possibly give a reduced anima rate for within your chosen area. Maybe half the cost of your area or something like that or if your in the area teleporting to the main city is free.

I just find right now having a GC has very limited advantages or at least nothing that makes your decision much different besides the area. I'd also think it would be neat if taking the airship from your chosen city would be free going out from your city but cost money coming in or from other areas.

I'd also be open to the idea of being able to buy more anima and since it takes a toll on the body maybe incorporate it into the inns and you can stay in a different room that cost more but regens some anima for a fee. I think your right that most casual players won't burn through it but alot of the end game players between the Moogles and Ifirit really can use alot fast and recently it's been kind of a pain trying to get everyone gathered between the two which can result in very long travel times.

After playing the game since launch is abit tiresome running through these areas. I think something does need to be done with the anima especially for those in several LS doing alot of these events.
