Figured I would chime in. Here's the way I see how things went.
Old Team: Hey, lets give them limited anima, so they will use gil sinks like choco's and air ships.
Game: Hi, I suck because I was released without most of my content, including choco's and air ships!
Old Team: We need to fix this! Lower anima costs!
Yoshi-P: You guys are derps. -.-
Old Team: Awe. Nobody loves me. T_T
Game: I still suck.
Toshi-P: Don't worry, Game. I got your back... Lets see what our peeps out there say... Hey players~!
Okay, so maybe I'm a little sleep dep right now. But that's the mental image I got. The point is that the teleporting was balanced with other modes of transportation in mind. For the casual player - which SE still wants to include in the game - the low cost teleporting is important. For the hardcore player, teleporting should be a game of managing your anima because you are constantly needing to use it.
What we know is that Chocbos and Airships will be included, eventually. This will reduce the need for Anima. As it is balanced right now, I suspect that it would be a problem because then there would less incentive to use alternate means. I suspect that the higher anima cost will be re-introduced, and we will keep our "preferred" destinations.
Now we will have to manage our anima even better, or risk having to use Choco's and Airships. This is a good thing.
I personally would like to see an implementation of teleport spells. We can reasonably assume we will see White Mage at some point, either as a new class (probably) or a replacement for what we have. But instead of giving White Mages the ability to do what we can already do, I would suggest we give them the ability to EXPAND on what we have.
This makes sense especially if White Mage ends up being an advanced job. If that were the case, maybe they can allow White Mages to gain an ability at some point that adds Aether Gates to their teleport list, and/or allow White Mage to do a group-return.
I personally believe that death should cost 1 anima (but not prevent you from returning if you are at 0 anima). This will not entirely eliminate death warping, but I personally believe that there should at least a minimal impact from death - which there currently is not.
Again, this will not affect casual players as much, as they are not traveling as much. But it will affect hardcore players. And, again my opinion, if you are hardcore, then you should be endeavoring to avoid death anyhow.
I would like to see chocobos implemented in two ways as gil sinks. One, transport for gil at a higher rate that works like teleporting in that it is "instant" between cities. That is, if I rent a "Chocobo Carriage" at a city, I get a little cutscene of me leaving City A and arriving at City B. Obviously, cost would have to be carefully balanced. This gives me a way to deal with the fact that I am low on Anima, gives me the ability to travel long distances quickly, but does not give me the ability to just go anywhere - that is, after all, why you want to manage your anima.
I would like to also see the ability to rent chocobos, as seen in 11. I rent a chocobo, I ride it wherever I want until I get off it. Like in 11, this provides a faster means of transport than walking or running. This also means that if I do not manage my anima well, I am stuck being slower, but I am not SOL in terms of getting places.
Airships are similar, and in the past have been used how I suggest Chocobo Carriages might work. However, I have suggested Chocobo Carriages instead. Why? Because of Companies. Unfortunately we do not know much about them, but it has been indicated that there might be company airships. I will go out on a limb and assume that these will be company-specific things that, in addition to whatever SE adds, will allow us transport similar to chocobo carriages, but without the per-use gil sink. I would even go so far as to envision that the "Fee" for such ships is a group of crafters in a given company that must maintain the airship.
Talk about killing to birds with one stone! "Free" airship travel for company members, and more stuff for crafters to do!
Anyhow, as I said all of this would require balancing with the current system, and is an addition to the system. There is no need to completely remove telporting - just a need to tweak it once other features that should have been in place are in fact in place.
2cents.
