I definitely found Orcish culture in Morrowind interesting - it drew many parallels with feudal Japan and other Asian influences that have since been rerouted into all this moronic Akavir hype. Most of the Orcs encountered in Morrowind were hunters, wanderers, hermits, and the like. They were pretty brutish - with many being armorers or weaponsmiths, but the occasional mage or political figure was seen as well. The problem with Oblivion is that it basically got rid of that first range of Orcs, leaving nothing but the civilized, bland NPCs that felt like recolored Nords.
Uh, no idea where you get this distinction. Not even counting in all those marauders, vampires, arena fighters and adventurers, but only the named chars, there are:
Sneaky types ..
* One assassin (in the DB)
* One pirate (on the Serpent's Wake)
* Three rogues
* Three thieves
* One savant
* Two Dark Brotherhood enforcers
... for a total of eleven of them.
"Noble" types ...
* Two semi-independant (Rugdumph and his daughter)
* Two in castle duty (Skingrad and Anvil)
* One priest in Chorrol
... for a total of five.
There are only
two mage-type Orcs, a nightblade (Mor gra-Gamorn) and a warlock (Magub gro-Orum).
Aside from that, there are three traders, two owners of a tavern, and nine farmers and the like.
Now, there are the following fighters ...
* Five barbarians
* One crusader
* Seven warriors + one trainer
* Two smiths
* One arena chamption
... for a total of 17 of them.
Now, keep in mind that most of the adventurers, all of the marauders and all of the arena fighters are heavy-armour fighters. So you have not only a good portion of the named (thus, already unusual and atypical) Orcs being your "stereotypical" fighter/armourer type, but also nearly everyone of the unnamed ones.
