[2020] Legendary memory dungeon runs

With a hotfix to the game that went live yesterday, we improved the drop rates of Legendary Memories relative to dungeon difficulty. Their Mythic difficulty drop rate is now significantly better than on Heroic, which is significantly better than on Normal.

More importantly – the drop rates for Legendary Memories are much higher in Mythic Keystone difficulties, and they ramp upward with the Mythic Keystone level. The availability of Legendary Memories should increase dramatically next week.
