Demonic Pact buff?

So im currently playing a destro support build for MC/all of the raids/content and its nice! I provide at max (with procs and trinket) 99 SP to the raid, which is huge! Main issue is imp is squishy and dies to aoe pretty often in mc/ony. The “buff” I had in mind which is a slight nerf would be from Demo. change demonic pact to add if the Warlock sacrifices a demon through demonic sacrifice their crits only apply 8% instead of 10%. I loose a decent amount of my damage when I loose my pet so this would be a nice trade off.

just add a shadowbite book for felhunters so they can actually do damage, kick, provide dispell support, and survive with innate fire resist."

please blizz

Shadowbite!
