Requires: Some program that makes clicks on screen, I downloaded myself "Auto Mouse Click by MurGee.com"
Spot: Shadowmoon Valley (55,74)

Macros (For warrior):
#1:
/targetenemyplayer
/tar Swamplighter
/startattack
/cast Revenge
/cast Taunt
/cast Heroic Strike
/cleartarget
#2:
/targetenemyplayer
/tar Swamplighter
/startattack
/cast Heroic Throw
/cleartarget
Keys: Put Macro #1 on Key 1, Macro #2 on Key 2, and some AoE Spell on Key 3. (It depends on your character, I use a warrior, you should adapt what your character is)
For example a Mage should put Ice Lance on Macro #1, then Arcane Explosion as AoE spell. No Macro #2 required. (It's just an example, there may be tons and tons of ways to configure it)
Another example would be a Protection Paladin: On Macro #1 Taunt and Avenger's Shield (And maybe a melee attack like Crusader strike or Righteous Strike or shit), on Macro #2 Judgement and another melee attack and then on Key 3 Consecration or something like that.
What Auto Clicker should be setup'd:

Press F6 to start farming.
It autoloots. (Remember to deactivate Click-to-move, and remember to activate autoloot), feel free to add more "Right clicks" where mobs die. But I think I put enough of 'em.
I recommend to monitor it.
Edit / After some tests: You'll get 1 level every hour, it only needs 2 hours to max it tho.
