Orcs vs. Humans

For Ereb:
My message considered the possibility of an Orc facing off against Light and Darkness at Haven. And that's it.
If you had immediately posted the entire build, my answer would have been more detailed...
In total:
3 racial traits - all
3 attack traits - tactics and retribution
3 defense traits - evasion and staunch defense
3 leadership traits - speed aura and battle frenzy
3 luck traits - soldier and barbarian luck
3 Light or Darkness suppression - all starting perks.

And what other artifacts besides the gnome artifact...?

For Lordesat:
Terrifying Roar is a great counter to Subjugate.
