With scheduled weekly maintenance on September 10, we’re going to reduce the effectiveness of a few new Class Tier sets that would otherwise overperform relative to our targeted values. We will also increase the baseline damage of the affected specs to account for the tier set tuning.

We will then look forward to additional tuning that we’ll develop during Heroic week, which will address anything needed for PvP, Mythic+, and Mythic raiding on September 17.
