If you explore the world, either solo or by group, then your (possible) reward is teleport ticket to that place. Maybe I'm misunderstanding some posts so please clarify why exactly it is a bad idea to have portals to other major cities.
if you are given access by default to other parts of the world, then exploration would be meaningless.
Limiting player options when they don't yet know anything and removing those limits gradually (by exploring) is good thing imho.
