Like you I did a lot of questing in the GFay area and found there to be somewhat of a low amount of mobs, whether its Orc Pawns or Pixies. I figure that with the lower number of players the spawns seem to be on par, however it can seem rather sparse at times.
The Pixies also drop their dust and I had considered doing the quest, but the NPC
Ran Sunfire is sometimes missing. To my knowledge the NPC is a female, although the quest says 'he'.
