Demon Skin is fine, our new soul leech is REALLY strong in PVE, so it was in PVP.
Rot and Decay was the root of the problem, according to some of the pro PVP's playing as afflic.
Unstable and Intellect was overnerf, at least by the ammount nerfed, but unless you play a lot and go on the beta forums/twitter, it won't change. I suggest every Warlock that likes to PVP to go there and say your thoughts.
