After rumors about this possibility for the last several expansions, Blizzard has finally followed through on a level crunch. Whereas characters in the current Battle for Azeroth expansion cap out at level 120, the cap in Shadowlands will be 60—just as it was when the game first launched and just as it is in World of Warcraft Classic. Level-120 characters will be scaled down to level 50 when Shadowlands launches.
Since this was an early questing experience and not an endgame one, I didn't get much sense of how Covenants—Shadowlands' new Order Hall, Garrison, or War Campaign-like systems—work. Neither did I have much time to dive into the story, though I saw enough to know that, if you like the flavor of the recent WoW expansions, you'll probably like this one, too. (I, for one, am glad we're going to get a brief respite from the Alliance vs. Horde war storyline.)
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.
Sometimes, the spirits roam the Shadowlands without resting. It can be because their resting place wasn't complete, because of a battle in their resting place or because of the corruption of their resting place. To bring eternal peace to the souls, it is needed to destroy the source of corruption or by making a ceremony with items such as [Tuskarr Ritual Object]. A spirit in the Shadowlands can, with enough power over other souls, tear a hole into the living world once they are strong enough. This is how Jin'do returned to Azeroth.
Keep raising the level cap but crunching how much experience is required per level as you do. This is the approach WoW has historically taken. But as this happens, levels start to seem meaningless. You gain them ultra-quickly, and only a smattering of them actually introduce new abilities or other perks. It also means that you blast through the leveling content at such a pace that you never finish individual zone stories; you only finish a small portion of an area before you have outleveled it and are ready to move on.
Sylvanas Windrunner, fallen leader of the Horde, has pierced the veil between Azeroth and the realm of the dead, setting in motion a series of events that threatens to upset the cosmic balance between life and death. World of Warcraft players entering the fabled Shadowlands will find the realms of the dead in upheaval. Under the normal order, departed souls were delivered to a realm appropriate to the lives they led, but now, all souls are being funneled into the Maw, where the most wicked are damned to suffer for eternity. As they seek to right the cycle and uncover the extent of Sylvanas' designs, players will forge bonds with the Covenants who hold domain over different planes within the Shadowlands.
