New changes in season 3:

Great Vault

• The "Mythic Dungeons" row has been renamed to "Dungeons."
• Heroic, Mythic 0, and Timewalking dungeon runs now unlock rewards in the Dungeons row. These draw from the same rewards pool as Mythic+, with lower item levels. Timewalking dungeon runs count as Heroic.
