Q:
Playing with my friend when nobody is in overflow.
A:
Not yet but I believe they are eventually going to add a “guesting” feature so players like you and your friend can play together.
You should be able to play together if you’re both connected to the “main” server for whatever zone you’re in, just as if you were in the same overflow server.
Sorry, should have clarified: We’re not on the same ‘home’ server, we can only play on overflow together.
Thanks! I looked it up on the wiki now. Sounds promising, exactly what I am looking for.
Side note that might not help, but from what I know, there is still free server transfers right now, so you could switch if neither or only one of you is tied down.
