Blizzard has released more hotfixes for the troubled Battle for Azeroth patch 8.0.

The Battle for Azeroth 8.0 pre-patch was deployed on the game’s live servers, and its launch wasn’t that smooth – something that has been acknowledged by Blizzard. While major updates almost always cause some issues, this pre-patch caused major login and account issues, and even worse, players are faced with overpowered enemies, item level issues, broken questlines and more.
