Not an insane guide, but a rather good one for making a few extra gold on the AH.
If you're an Alchemist, you'll have the recipe: Living Elements.
This requires you to take 15 Volatile Life, and then transmute them into a [random] volatile of a different type.
We can make sure that we get a certain kind, however
Do the xmute in the followings zones for the following elements:
Xmute 15 Volatile Life in Mount Hyjal = ALWAYS turns into Volatile Fires.
Xmute 15 Volatile Life in Uldum = ALWAYS turns into Volatile Airs.
Xmute 15 Volatile Life in Vashj'ir = ALWAYS turns into Volatile Waters.
Xmute 15 Volatile Life in Deepholm = ALWAYS turns into Volatile Earths.
Have fun
