Hmm. I'm not sure of what is going on for you. I had a character hunting Sand Devils just a couple of months ago, and I had no trouble finding them. I don't recall ever going more than 30 or so seconds without finding one and frequently had three or so in the area at once. They are pretty tough due to the automatic sandstorm attack, so if I were still hunting there, I don't know that I'd want to have the gen rate turned up much.

<If you are moving in and out of their zone, and there's no one else in their zone to keep spawning switched on, the overall rate will be terrible because you'll keep switching them off.>

There's a number of critters like this.... I see people in the Citadel all the time wandering the entire place looking for swordsmen, but they only spawn when there's someone in the dungeon.
