As a returner, you will be allowed access to the Novice Network. This is a chat channel for players new and returning to ask questions and help from veteran and seasoned players (mentors). You can also try the Hall of the a novice to practice basic concepts of the role you are doing for team play. You might as well get Stormbood as that comes with Heavensward versus just getting Heavensward. You will not be lost with the MSQ as the game will direct you now what to do next. The MSQ and will not be enough to level up to cap, but you can do other leveling features like roulettes, clan hunts, challenge logs, fates, and (up to 60) the POTD.
