As mentioned in this week's PTR Development Notes
, there are several changes to Mythic Keystone Dungeons now available for testing. We'd love to see any feedback you can give us regarding these changes, including the new dungeons, new and updated affixes, Artifact Power redistribution, and anything else you encounter that you feel is worth sharing.
Note: There is currently a known issue with Upper Karazhan Keystones which is causing you to start the run in the wrong location. We'll get that fixed in an upcoming build, but for now, we're going to hotfix the door that requires Moroes' Keys to be open by default, so you can progress through the dungeon that way.
