Natimbi->Quinimi->Riwwi
Kinda like Quinimi with harder mobs. The arena area is pretty cool with some named mobs that can spawn there. Named mobs hit 900+, but really aren't too bad with a decent group. Decent XP.
I made a ton of money there before OOW, but the items from OOW pretty much trivialized the loot from Riwwi - most of the stuff from Riwwi has required lvl of 55.
