Along with the release of the Demon Hunter class, Blizzard also kicked off the Demon Invasion event in which players level 10 and above will be able to take part in trying to fend the legion invasion off. Players who have hit level 98 will also be given a quest that will take them to the Broken Shore, a new scenario that will let them start questing in one of the new zones for the Legion expansion.
We should point out that this release isn’t the expansion, or at least not entirely. The Legion expansion for World of Warcraft is still set for the 30th of August, but the release of the Demon Invasion event will act as a transition into the new expansion. The event will only be live until the release of Legion, so whatever rewards/achievements that you want will only be obtainable from now until then, so maybe you’ll want to hop on if you haven’t done so already!
