With the first week of timewalking having started, it seems the dungeons are having some scaling issues with player gear, as it is being scaled down more than intended. A hotfix should arrive “as quickly as possible”, but there wasn’t a note in today’s hotfixes saying it was resolved.

Hey all,

We are aware that the gear level in Timewalking Dungeons is currently being scaled down more than intended. We are working on a hotfix and will deploy it as quickly as possible.
