I just confirmed that yes you can run Guild Wars 2 from an external drive. I plugged in an external USB 3 HDD, moved the Guild Wars 2 file from the Applications folder to the external drive, double-clicked it, downloaded an update, logged on, and everything worked fine. If you wish to run Guild Wars through Steam (and use the Steam Overlay), you should uninstall your existing, non-Steam, copy and then use the 'Install' link on the 'Guild Wars' page of your game Library to install the launcher. Be sure to back up your existing 'Guild Wars' directory (containing screenshots and saved skill templates) from My.
