Extra damage from the Gargoyle
For PVE, we have seen some pretty decent numbers come out of Requiem Lant Blood. I think players just need more time to try out all the build combinations. For PVP the big hits of Scourge Strike, the mitigation of Bone Shield and AMZ and the extra damage from the Gargoyle and ghoul probably make Unholy overshadow the other trees. This should be better next patch.
