This is sorta obvious... but its really good
In silithus, if you go to the northwest corner, there are 3 different kinds of elementals, and they all drop GREAT ah items... what not many people know, is that the drop rate on essence of air (1g a piece) has beein raised a crazyyy amount. off a normally 7% drop, i got 7/10 times a drop... in only 3 minutes (at 60!) this is best using a mage, since you can aoe about 10-15 of these at once (if youre 70)... my mage friend got about 20g per pull! and the pulls take about 2 minutes!
