Necromancer Ascendancy Advice

I kinda just need help understanding my options...

Running Skeleton Mages, so I kind of figure Unnatural Strength is not going to be useful for me, so that's right out. Mages don't do physical damage at all do they?

Command of Darkness looks like it'd be good, maybe even honestly comparable to Mindless Aggression. They do about the same thing except one gives some extra movespeed, to my minions, and the other just gives us both some extra elemental resistance. I guess that's nice, since it'd make gearing easier...

Bone Barrier seems cool and all but I am already using Molten Shell.

Essence Glutton is an ES thing and I'm focusing on raising life, not ES.

Plaguebringer sounds like it could be useful, I mean there's almost always going to be corpses around and 10% more damage is nice.

Corpse Pact and Mistress of Sacrifice both seem like they might be okay if I were going to be eating a lot of corpses but I don't know if that's going to be the case since I'm kind of just freewheeling this build and making it up as I go along. I might eventually get some auto cast Desecrate/Offering combo going but I don't even remember how to do that, just that it was kind of possible a few expansions ago with a wand craft, or something.

So like the only valuable things, immediately valuable, seem like Commander of Darkness + Mindless Aggression and I have no idea where to go from there.

Thoughts?
