A lot of things in MMOs rely on getting to where other players are at the same time as many other players, to make a "massive" multiplayer online game, and the new system really makes that a problem. So its certainly an odd change to make and I hope they remove these restrictions soon.

I also hope that they also continue to improve the world visit system for worlds on your DC, as its currently easier and faster to visit another DC (so long as it isnt locked under the new system, that is) at only 1-2 minutes travel time, but it can take over 5 minutes during times like a hunt train forming for you to travel between worlds on the same DC.
