I have to actually see what Yoshi has in mind to give a real opinion, but if it is just willy nilly teleporting everywhere all the time I'm going to hate it. At that point you might as well just turn the game into a quest hub where you queue up for group and then click a button when ready to zone into the dungeon. There is zero reason to go through all this trouble to create a new world full of beautiful zones if nobody is ever going to experience them.
