I, personally, would like to see a lot more of the game mechanics handled in the same way a dungeon master would handle them. Looting, for instance. I'd like to see one roll for "investigation" when I loot a corpse, which also loots all other corpses within the room. No self-respecting DM would roll individual loot for each of the 30 goblins that attacked the party. Well, unless they're a masochist, in which case; all the power to you.
