Unable to Access Heroic Darkshore Warfront

In order to enter the Heroic Darkshore Warfront, you will need to Interact with the War Table in Boralus or in the Port of Zuldazar with your raid group to join the fight. Note that the option to queue for Heroic Battle of Darkshore will become available when the next time a certain faction commences an assault on Darkshore in a given region. Regions that are already partway through a Battle of Darkshore attack cycle will be able to access Heroic difficulty the next time Darkshore comes under attack in Season 4.
