I wasn't really going to post this because I thought that I will have everyone spamming me saying "OMFG common sense" and "this is stupid" buuuuuuut if I can help at least one person, then im happy. so here goes.
While leveling in Scholazar Basin I came across a village of Frenzyheart people while doing a quest for the oracles. They are called Frenzyheart Hunters (Creature: Frenzyheart Hunter - Thottbot: World of Warcraft) have very little health, do little damage, respawn practically instantly, and drop the normal amount of silver as any other mob (5-15s). They also drop runic mana/health potions and the occasional scroll.
If you do any of the oracle daily quests for them, particulary Power of The Great Ones it helps alot for much faster kills.
Im not recomending grinding here as level 80 or anything, you can get more gold doing dailies, but it is a neat little place to go to as your questing/walking past, and the best bit about it is you can get 20-30 people at once, and as a lvl 80 DK, I find it fun as all hell
