Favorite off-beat leveling locations?

[Striiker]

Here are some areas in which I have hunted.. (sorry in advance for it being poorly organized.. I'll come back to clean it up later)
I did blackburrow until around 12 via the Gnoll fang quest.
Wisp Island (Erud's Crossing) from 12 - 16? Saved the GLS and did a turn-in to the gypsie in North Karana (and sold the book you get)
West Karana scarecrows from 14 - 17 (did these for their solo-ability with my necro)
Befallen from 12 up to about 18
Unrest 14 - 30 (yard trash first, then to pulling to wall in the back, then to Main Room, then to Fireplace, then to basement)
SolA low 20's to 32 Mainly on the non-castle side.. so foreman, predator, singe areas..
Upper Guk in my low to mid 20's
Cazic Thule I think from 20 on up to about 40? I've grouped here only a few times in my 30's.
Mistmoore - 20ish starting out front. at around low 30's doing the Castle Entrance, Grave Yard or Pit.
SolB 35 + Starting in the window room and royals..
Lower Guk (haven't done a whole lot here yet.. mainly the Assassin / Supplier camp when I've been here. Started here in my mid to upper 30's.

I have avoided the grind-fest places like South Karana, LOIO, Overthere, DreadLands. I did those on live back in the day and it gets old very quickly. I prefer the challenges and risks in the dungeons.
