To help you get prepared for the upcoming Warlords of Draenor Patch 6.0.2 release, we’ve uploaded the patch data to the background downloader. By downloading the patch in advance, you’ll be ready to get in-game and start playing as soon as the expansion goes live!
If you have issues during this process, you can find help to resolve them on the support site here.
You can adjust your download settings within the Battle.net desktop app by clicking on the Battle.net symbol and selecting “Settings” from the menu. Under Game Install/Update you’ll be able to adjust your download options for each of your games and enable or disable the background download, adjust the rate for your download, or pause it if you have a restriction on daily downloads.
