Blizzard has posted upcoming class tuning on the Weekly Reset which includes nerfs to Frost DK, BM Hunter and Warlocks, combined with Ret Paladin nerfs in PvP.
In patch 10.0.7, we made changes to several classes to address issues we saw with itemization or talent trees. Game data since the patch went live has shown us that certain specs are overperforming, so with scheduled weekly maintenance on March 28, we’ll make the changes below.
