So I was just reading through the recently updated dev blog found here https://na.finalfantasyxiv.com/pr/blog/002726.html

So far they list the can/cannots of world visiting:

You can:
  • Accept/Progress/Complete Quests
  • Party with other players
  • Queue for duties
  • Purchase items from Marketboard
  • Use FC/PVP chat channels
  • Use cross world linkshells
  • Visit friends
  • View player housing
  • Join player events

You'll also have a wanderer tag when visiting other worlds on your nametag. They didn't list any cannots. Guess that's coming when the play guide is updated as mentioned in the blog.

I'm super excited about the marketboard and being able to group with other players. It was a good move to leave out selling on the marketboard (I imagine because of RMT stuff). I can now see myself hopping worlds to find the lowest price (or available) item I'm looking for. The undercutting will be even fiercer now!

Also used to be on an FC in Ultros, and I can now go back and visit with friends on that server which is beyond incredible.

So what are your thoughts on the cans of world visiting?
