Thoughts, ideas and desires:

(More?) Non-random items.

Perhaps some sets gain (or grant) (extra) magical capacities if all the pieces are worn/wielded.

The Dragon set could, when complete, give you some kind of fire spell, and raise your strength and constitution. (Only while all pieces are worn)

Reactions to impressive appearances:
Some specific items might have a set of comments like... like wow! (Get it?)
And sets too; people in full dragon suits don't come by every day.

If you come riding into town on a white mare, in a beautiful suit of armour, perhaps people could assume you were a knight, simply on appearance.

Perhaps people who don't know you well won't recognize you if you wear a closed helmet.

Oh, and correct the settings on offense/defense to 'traits'. I remember having 57 offense: "Since you're not likely to hit anyone..." (I walked through an army of orcs and left loads of loot for the way back. It looks rather amusing, in its own way, when an orc veteran comes charging and the hero doesn't even seem to stop walking, only swings his sword once and fells the beast...)

If DD2 is a continuation of DD, then perhaps the DO (Divine One) would have assembled a new council and ended the hostilities between orcs (and imps) and other races? Make it a bit more obvious that orcs are not evil. Bring foes from a new angle. But thugs could hail from any race, of course.
