The long sought after feature is finally coming!
With an update on January 28th, server guesting is going to be implemented, but what does it really mean?
Guesting a server only gives you access to the PvE content of the server you choose to guest. Trying to join a WvW map will move you back to a WvW map on your own server.
More importantly, you can only guest servers from your own region, so if you want to change from European to American servers, or the other way around, it is a good idea to do it while it's still free.
