Im going to head to Uldum first. I find the beauty of the desert and tropical river areas beautiful. Its a good idea to set your hearth portal to somewhere close to the Orgrimmar or Stormwind Cataclysm portals. In the case of the character I am useing I like to set her hearth to the Dwarven District , so I can hearth back when I need to sell.
Fly around Uldum at this point and go get rich.
In the above screen shot I am highlighting some water elementals that need to die. They produce 1 -4 Volatile water each when you loot them. I like to aggravate a ton of them gather them together around my mage and rain of frost on them so I can multiple loot . I then follow the below map of Twilight highlands and groove on some toons as I mine.
In twilight highlands it is best to follow the rivers and lake shores as you mine. You can maximize more profits by following the edge of the peaks also to get more ores.
I highlighted my paths. Find your own groove and set up a repeating pathway and play some toons and mine. AS you go you will find other elementals . I marked them in red. But the electrostatic condenser will do a lot of the heavy lifting as you mine as it gathers Volatiles. If you can find deals on the Auction house for the truegold ingredients.
