The gold worldpass is something that allows a person join a specific server and links their char to anothers on that server. You both get some items as time progresses. The world passes, gold and regular, are pointless as they started allowing people to choose a server to join. The items, just from what the OP said, are more so for their own benifit. Just enjoy the game and gl with the LS.
