Who would win?
A Orc Berserker decked out in a set of Orcish armor, wielding an Orcish war axe in one hand and an Orcish Shield in the other.
OR
A Nord Barbarian equip with scaled armor,bracers, and boots, wielding a Nordic Greatsword.
neither character is dovahkiin or has the use of magic or enchantments it is a simple battle of braun versus braun.
Orc, hands down. But maybe I am biased...
I could see how the reach of the greatsword might be a big advantage, but berserker rage or shield charge or shield bashing or stacking on fast bleed attacks is enough to take down anything. Especially since the Orc would probably get defense bonuses from actually wearing a full set (heavy armor) while the Nord leaves his head wide open to be split in two.
If the orc gets berserker rage, then the nord gets to make the orc flee like a little bitch (Battle Cry), striking him all the while. One can shield bash and shield charge with the great sword... (but now we're looking at 'perks'). (But I think the nord should get a helm too though).
