Title. I made a sick orc whom I want to be a pure warr with no block, probably dual wield. Swords, maces, or axes?

Use whichever you think works best in combat.

All 3 are different as are the perks.

I'd go with axes!

Axes are the worst in terms of actual power. But that's the most orcish. Maces will do a lot damage, ignoring 75% of opponent armor.

Anything as long as you use orc stuff

Keep in mind though that armour is barely a factor, since most opponents only wear non-upgraded Fur or Studded or something, and dragons don't have any armour.

OT: I'd go with swords, since they're the coolest looking if you ask me. Besides they are the fastest, which appeals to me.

I played on master difficulty with both blades and maces. The 75% armor ignoring is huge. It became a lot easier to kill everything but unarmoed animals with maces compared to blades, only against animals did I use blades. In the end, that small additional damage you gain from a critical hit is smaller than the added damage from 75% armor ignored the maces get.

Besides, there are plenty of bandits wearing iron and steel armor, and some bandit chiefs even in steel plate. I actually ran across one lone bandit on the road in dwarven, although that's only happened once. Met a couple thieves in elven armor. So armored opponents aren't as rare as all that.

That said, started looking at axe-and-sword dual wield, just because the game's "mascot", so to speak, does so. Took one perk in the sword critical hit thing, then I abandoned dual-wield for axe-and-shield, with plenty of perks in block and two perks so far in bleeding damage for axes, because I figger a Nord should swing an axe.

I went for two-handed axes. Then I trained one-handed maces and used two for dual-wield. Now my Orc is more of an archer who spends most of his time sneak-shooting, with his two-handed axe strapped to his back. He's now capable of using those weapons to the fullest of ability.
