At a certain M+ level, dungeons should start dropping Mythic dungeon loot instead of Heroic dungeon loot- or at least have a chance for it. It’s crazy some people are doing +22’s and are still getting irrelevant (for them) heroic gear. Mythic raids drop mythic raid gear and M+ relies on vault RNG on a M+ loot table. Mythic raids still have bis trinkets, some rings and mounts.
