Is this a particular quest that someone gives?
 
What about the Feerott instances for Tearable Fear/Fall of the Tae ew?
 
If Fall of the Tae Ew instance has repops, that's news to me. I used to do that a LOT and never saw the pyramid mobs ever repop.

Of course, there are a TON of mobs in the zone, most of them unrelated to the quest task so you could hunt those as well. But in terms of repops, this instance never used to.
