These are the Warlords of Draenor Mythic+ dungeons that will be in Shadowlands Season 4
Shadowlands Season 4 is going to add a selection of dungeons from previous expansions to the available Mythic+ pool -- the two wings of Tazavesh from the current expansion, the two wings of Mechagon from Battle for Azeroth, and the two wings of the Return to Karazhan mega dungeon from Legion.
Iron Docks quest hub postponed until patch 6.2
