I'm happy to see Blizzard making these improvements to Diablo III. So far, almost everything they've done has been a vast improvement since the game first came out.
That said, today a hotfix is going out to all the servers today to change up some of the mechanics of looting. Unique monsters are going to drop less loot, but that's OK. Chests are also going to be less frequent, but again, that's going to be OK.
The chances of finding a legendary item will now double when you are in a rift, making those areas a lot more profitable to farm. Now, folks are going to be more apt at doing rift runs over killing unique monsters when trying to farm for better gear.
Kadala is also getting a change as she's going to be more apt at giving you a legendary when you trade in blood shards. Good, because I've probably gotten one so-so legendary from her after giving her about 500 shards. I'm glad she's getting an increase in chances of giving out a good item.
All servers in all regions should be updated by the end of the day today.
