One of the big pieces of news about World of Warcraft: Battle for Azeroth is the addition (FINALLY) of a new battleground called the Seething Shore. It is currently live on the PTR and WoWhead has posted a terrific new fly through video to show off the environments players will encounter. In addition, a second video shows off gameplay on the battleground that provides a first look at some of the mechanics involved.
From the Battle for Azeroth / Blizzcon page:
In a new Battleground, Seething Shore, players of the Horde and Alliance will descend upon Silithus to battle over the Azerite bubbling to the surface. This Battleground will offer dynamic control point gameplay similar to Arathi Basin, but with new control points appearing periodically as resources are depleted. This new Battleground will require coordination as you and your team work to overcome the opposing faction. Since this Battleground actually serves to tell part of the story that leads to the events of Battle for Azeroth, we also plan to offer a preview of the Seething Shore during patch 7.3.5 as we continue to build upon the conflict between the Horde and the Alliance for the coming expansion.
