1) Fuloran's Abode
2) Festering Hate Pool
Fufu's was the very first "dungeon boss" in MMO's imo. I remember the first few times I did it how scared I was and how fun it was doing it with friends.
FHP is my 2nd favorite because this was the place I found my very first Wrath. Also it's the dungeon me and my 2 best friends leveled at for a long time. Brings back a lot of fond memories.
My solo hunting spot was Holy Caves with a "choker" toon.
