Heavensward builds on the foundation of A Realm Reborn and offers a somber and intriguing story in all new environments. With an increasingly toxic community, something does need to be done to curb bad behavior before it ruins the later parts of the game. If you've already completed the base game of FFXIV, there is no doubt that you need to explore the large and enjoyable expansion.
