Skills and Super Ability of the Orcs.

I really like the Barbarians, and here's my setup when I play as them:
1) Attack – Barbarians need attack!
2) Machines – Ballista, Rapid Ballista, Tent (sometimes Catapult).
3) Luck – Resistance, Soldier's Luck, Barbarian Luck.
4) Logistics – Pathfinding, Path of War, Death Stride.
5) Battle Cry or Education – whatever I get!
