I have a feeling teleporting will be changed in 2.0 after seeing one of the athes get destroyed in ifrit quest. In one of the 2.0 pics there is a pic of a warp machine similar to ff11. I don't think they would limit it to mages though, but I'm sure there will be far less nodes with smaller maps.

As of now just leave it alone, there's a reason were getting new maps. Cause the ones we have suck, so why would I wanna immerse in them.
