From now on, you should see Legendarys in the dungeons of World of Warcraft: Shadowlands more often than before. Blizzard Entertainment has recently released a hotfix that should significantly increase the drop rate. You can find the patch notes in the message.
Even before the release of World of Warcraft: Shadowlands, it was clear that you would be able to obtain legendary items in the new MMO expansion a little easier than in the past. After all, it is now possible to create these items on your own - provided you have the necessary resources. However, this is exactly what many players failed to do until recently. The reason: The "legendary effects" - probably the most important resource for this purpose - were extremely rare to find as loot in dungeons. This is to change with immediate effect.
Blizzard Entertainment released a new hotfix for World of Warcraft: Shadowlands last night, which is supposed to increase the drop rate of "legendary effects" in dungeons. This is higher on the heroic level than on the normal level, and on the mythic level they should be found even a tad more often. However, the likelihood is highest in mythic dungeons where a keystone is used. The better the stone used, the higher the chance of finding a "legendary effect" as loot. Here's the full list of changes from the latest hotfix.
Valfir the Unrelenting has bolstered his defense, making oncoming attacks much less effective. Players that wish to take down the beast will first need to send anima to this location to unlock the key to Valfir's demise.
Valfir the Unrelenting will no longer wander quite so far from his spawn.
Dungeons and Raids
Increased the drop rate of Legendary Memories in dungeons.
Completing Battleground objectives will now provide credit for the weekly PvP quests, "Observing Battle" and "Observing War.
PvP World Quests will now count for the associated zone's defense Callings.
Professions
Increased the cost of the following reagents to 9 Gold:
Increased the amount of vendor reagents required for crafting several Shadowlands armor and weapon recipes.
Crafted Shadowlands weapons and armor now yield less Soul Dust when disenchanted.
Reduced the number of vendor reagents required for Relic of the Past IV and Relic of the Past V for all professions and expansions.
Jewelcrafters will no longer lose the "Jewelcrafting: Gem Studded Bangle" World Quest recipe when they leave and return to the world quest location.
