The nerfs were really good except for sac pact. The card is now an anti draw of 1 a loss of a 1/1 and the reward is only 5 health. Warlock got hit hard because they dont have really good replacement options for sac pact or albatross. Sac pacs health shouldve been increased to 7 or 8.
Aggro DH got nerfed, but with the sac pac nerf youll see more DHs on the ladder and more decks that counter DH that are not warlock. There should be fewer OTK DHs but more mid range DHs with Priestess
The albatross nerf hurts warlock more than rez priest. Rez priest might still run albatross, and with the battlefiend nerf rez priest should see an uptick in play, which will lead to an uptick for rogue.
