This section contains information that needs to be cleaned up. Reason: The death knight realm has already been confirmed to be the Shadowlands. Sylvanas committing suicide from ICC in EoN has already been connected to the Shadowlands. Reword still unclear things, move confirmed things to the main section of the page or remove them entirely if they are already incorporated there.
Further, once the new character has completed the starting zone, the player can then choose to level up to 50 in any previous expansion of their choice—vanilla/classic, The Burning Crusade, Wrath of the Lich King, Cataclysm, Mists of Pandaria, Warlords of Draenor, or Legion. The expansion's content will scale perfectly with the character level, and each is tuned so that reaching level 50 involves playing through the content at a similar pace to a similar level of completion as those expansions offered when they were current content.
World of Warcraft: Shadowlands marks the eighth major expansion pack for the storied MMO. Judging from a half-hour playing it at BlizzCon this year, it seems like a natural evolution of modern WoW that will run alongside the very-different WoW Classic experience for the foreseeable future. That said, the biggest change wasn't part of my hands-on demo—but don't worry, that won't stop me from geeking out about it in extreme detail.
Frankly, the aspect of Shadowlands I'm most excited about is an overhaul of the leveling system—something that wasn't a part of this demo in a major way. This kind of breaks the rules of a hands-on article, but I want to take an opportunity to talk about it and why I think it's interesting, regardless, since it came up in my interview with WoW developers.
It's hard to get a sense of an entire World of Warcraft expansion from 30 minutes of play. In my short demo, I recreated my main (a Beast Mastery Hunter) and played through the introductory quests from the Bastion zone, a heaven-like plane from Azeroth's afterlife. The minute-to-minute gameplay very much followed the formula of modern WoW questing, with a variety of tasks like challenging specific enemies to duels, helping craft things in timed minigames, and of course, killing 10 rats (well, not rats, but they might as well be).
Claim a covenant's power: players will be called upon to forge a bond with one of four covenants that rule Shadowlands' new zones, setting the tone for their journey through the expansion with a full covenant campaign. As they level up, they'll get new abilities based on their choice, including class-specific abilities for each Covenant—as well as developing soulbinds with specific covenant members, which grant them access to that character's specific traits and bonuses.
