Primal Air Farming

You can farm Primal air by farming Motes of Air which mainly drop off Air Elemental type mobs. You can also get them from Gas Extractions, but it is recommended you just kill for them. The best places to farm are in Nagrand or Shadowmoon Valley. If you are looking to kill mobs in the range of 63-67 to farm motes of air then you can run around mostly anywhere in Nagrand killing Storm Ragers (64-66), Dust Howlers(63-65), and Living Cyclones(65-67), but if you are level 70 or have a flying mount/warlock to summon you to places then you will want to go to one of the two places in the maps.
