I'm not sure if there are enough mobs for multi-boxing but the yetis on coffee bean mountain were insta spawn in the caves. Eating the coffee bean was like perma bloodlust/heroism buff with run speed and they stacked to 100. The game won't let you eat one if the buff is still active so putting /useKafa'kota Berry in your macro kept it up. The caves were littered with the berries. This is how I power leveled my Paladin and Shaman. Loot was meh.
