10/10 good takes. My suggestions for Demo are as follows:
Bake Imp-erator into Imp Gang Boss.
Bake Demonic Brutality into Tyrant.
Bring back Borne of Blood but at a reduced rate,
Have Soul Strike do more damage on execute phase but take away the Soul Shard gen.
Bake in Doom Eternal to Pact of the Ered’ruin.
Have the Doom Guard’s Doom bolt from pact cleave.
Finally, buff our Mastery.
