It’s often been said by A-Net that the social aspect of the game is of great importance to them, however this implementation of guesting unfortunately contradicts that. In GW1 it was very easy for EU and NA players to game together and, as a result, many guilds (like the one I belong to) formed with members from both zones. The separate EU/NA servers of GW2 effectively forced us to split such guilds (because who wants to play on a server that is dead during their peak playing hours?) but my guild had faith that the promised guesting would provide a workable solution to that. But unfortunately it sounds like this will not be the case and the separation of EU and NA players is now much more permanent. Not happy, ArenaNet, not happy at all…
