My and a friend wanted to start playing Guild Wars 2 together. Both of us selected the same server and created our characters. Once in-game, we opened the Contacts menu with Y, sent each other a friend request, and joined a party.
However, despite being friends with each other and joining the same party, neither one of us could see each other in-game. A few posts online said I should be able to join my friend's instance by selecting "Join server", but when I right click my friend's portrait this doesn't appear as an option.
How can I start playing Guild Wars 2 with a friend? Do we need to complete the tutorial before playing together?
