There was one quest that I know of that used it.  It was in GoD I believe.  You did some run around quests in every zone and got this one drop from the boss of every zone and it was very skill intensive and at the end you got either a good augmentation item or a good range slot.
When I left in the game this was the longest quest ever in the game.
