Affliction nerf?

So, the other day I was stomping peeps in BGs on my affliction warlock. In the 10-19 bracket and then the 20-29 bracket. (Still 26) My DoTs were shredding, my Malefic Rapture was hitting for about 500 damage. The world was good…

Today however, a full round of my dots without any healing or damage reduction, has been bringing people barely below 90% of their hp. My malefic Rapture HAAAA, barely doing 100 per cast with all my DoTs on a target. The day before I was shredding groups of 3, popping off all DOTS, then knocking out all my Malefic Raptures and killing em all ggez, no prob.

Did Blizz secretly nerf aff damage or something? It’s a noticeable difference in damage.
