I'm Worried for GMS

If I am understanding this right why not just add a different "ticket booth" for every place? Only japan still has that and some versions of the floating market.

Thats the whole point of removing Spinnel X_X it forces that contents creator to rethink how the player gets to the area that has been added. With Zipangu, they could easily have a connection from KFT, or something. The way it is now puts everything in one place and it removes the idea of "touring the world," as you arnt moving much to get there. You click someone, and your there. Thats why NLC and Singapore work, you seemingly travel there by the subway or train.
