With the upcoming Season 4 and overall rework of M+ dungeon rotations in Dragonflight, it may be confusing for players to find all of the guides, or loot rewards from all the different dungeons, so I suggest that a new window should be created for Mythic+ in the Adventure Guide:

Another issue that this could solve is the confusion about the mega dungeons that have been split up for Mythic+, so players would not need to use external websites to know what bosses are in which dungeons:

This could also be a great way to showcase what Item Level each Keystone Level rewards, including the Great Vault levels, so we could know what stats each items have at high item levels:
