According to Icy Veins, Service is actually take-able for Affliction, Demo PvE too, "In fights with mechanics that grant a temporary increase to your damage". I don't raid so I have no clue which fights those are, but apparently it's not useless entirely. Also, if Demo wants it for the Extra Fury generation (guessing during Dark Soul) isn't using Wild Imps enough, with Supremecy's blanket DPS increase leading ahead?
Personally, I think the Grimoires really break the "Take what you want" mentality. Sacrifice was never geared towards Demo, and it seems to be pulling ahead in PvE with every else to make the other ones useless. Also, Netherspark, I think Demo has trouble with choosing demons other than Felguard in general, not just with Service.
