This farm almost did not make this list. Even though I have had only a little luck with it, it seems to be gathering some popularity in the gold farming community.  Although I feel with the recent changes in 7.3,  this farm is very close to dying out.  Generally what you want to to do is pull every mob you can as you venture to the last boss in the instance.  The only saving grace of this farm (if you can call it that) is that some mobs are GUARANTEED to drop greens.  Guaranteed.  Whether or not they drop profitable greens is a different question, however it's a must-mention quirk you get from running this instance.  It also allows you to get your hands on some rare low level blues.

40% of the book is maps with notes (useful always). 30% is detailed descriptions of the classes and their skills and spells and tips for playing them (useful when starting out). 10% is a list of items and monsters in the game (not very useful). 5% is an extension of the manual, telling you how to do things (useful). 5% is how to get started in each starting area (I haven't used this.). 5% is play tips (useful mainly to beginners). 1% is abreviations and what they mean (useful mostly to beginners). 4% is miscelaneous information.
Awesome trick really.  In this farm we'll be taking advantage of game mechanics to exploit a way into getting more defias loot drops.  The defias leggings and gloves have respective selling prices of 3,000g and 14,000g and only drop from 1 mob in the instance a staggering 1% of the time.  But do not fret, we can get the upper hand on this.  Much like past drop-combat farms, if you kill just one of the two defias overseer's in the instance, THEN drop combat, the one you killed will instantly respawn.  The trick here is to bring a character that can consistently drop combat and score many more kills than the average farmer.  To date, a hunter is best – with night elf being slightly better because of shadowmeld.  You can also bring potions of invisibility to boost the effect.  Anyway, while the average farmer only gets 1 shot to get these super rare xmogs, with this method you can get up to 40 chances in an hour.  Seems fair right?

Finding the best route for you can be a bit tricky because of the size of the dungeon. I will usually only do about half the dungeon, killing as many mobs as I can in 6 minutes. After 5 minutes, make a group in the group finder and leave it. That will leave you a minute to complete your 6 minutes and you will be ported out on the 6-minute mark, ready to reset and port right back in.
The vanilla WoW Horde leveling guide you see on this site was originally made back in 2006 by Joana (AKA Mancow, or FuriousPaul).  The guides have been tweaked many times over the years to make things "faster".  The leveling guides were made because of all the messages I got from people asking me how I was able to level up so quickly on new realms.  I was first to level 60 on 7 different realms (3 with Mancow and 4 with Joana), even winning Blizzard's "First to Level 50" contest they held back in 2006.
