•Kezan will be the first questing zone for Horde players. They will find it mostly in ruins and abandoned after the Cataclysm. Horde players will have to fight through the Isle and reconquer Undermine, making it their main city for the expansion.
•Undermine was also heavily considered to be the main neutral city, as seen in the last leaked email, but it was difficult for the team to think of another unused iconic Horde location to serve as theirs.
•Kul Tiras' peninsula will be the same but for Alliance players, beign Boralus their main city. Alliance players will also find the zone heavily damaged, and will have to defend the isles against a Naga assault, securing them once more for the Alliance.
•It is said that Jaina Proudmoore will most likely be the new leader of Kul Tiras, but the posibility of bringing Tandred Proudmoore to canon is also pointed out, though not well recived.
•Since Kul Tiras is formed by different islands, other zones are mentioned to be possible parts of the Horde's questing experience, such as the Lost Isles or the resurfaced Darkspear Islands, where we could meet one of Vol'Jin's sons as part of the quest chain, who would eventually take the mantle as leader of the Darkspear.
•Tanaris will have a new phase, like Theramore and Blasted Lands, featuring a Hearthstone-like Gazgetan, making it the main Neutral City for the expansion and the Capital of the Steamwheedle Cartel, since Undermine is now part of the Horde.
•It's beign discussed what would happen to the players hated by the Steamwheedle Cartel, and while some of the developers are thinking of making the new Gazgetan phase neutral to them anyways (thus ending also the posibility of players killing the city's NPCs), some of them are sugesting to let those players go to Plumber Isle, since Gazgetan isn't going to be a focal point of the Expansion unlike Dalaran in Legion.
•Kul Tiras and Kezan will allow the players to travel to the leveling zones and their Capitals (Stormwind, Orgrimmar, and Gazgetan/Plumber Isle), and will have a Shipyard like the one on WoD's Garrisons, where the players will command their faction's navy and send them to quests. The Shipyard and the main city will also have a campaign like the Legion's Class Hall ones.
