One thing that has always been remarkable to me in World of Warcraft is how it brings players together from all sides of life to meet with common goals. I've been playing the game for fifteen years, and have played with gamers with all sorts of accessibility needs. I distinctly remember raiding Serpentshrine Cavern back in the day with an amputee friend Paladin who healed an entire raid of 25-players using a mouse equipped with dozens of buttons. He also competed at a high level in World of Warcraft Arena, as well as any able-bodied player I've seen.
The Shadowlands will feature five major zones - Bastion, Ardenweald, Revendreth, Maldraxxus, and the Maw. In the center will be the city of Oribos, which functions as the main player hub similar to Shattrath City in Outland in The Burning Crusade or Dalaran in Wrath of the Lich King and Legion. There will be four new dungeons for leveling, four more at maximum level, and a new raid. In addition, a new roguelike "endless dungeon" called Torghast, Tower of the Damned, will be introduced for both solo and group play.
