Ok this guide can make some sweet gold, what you need is 375 Fishing, a flying mount (I recommend an epic) and Aquadynamic Fish Attractors.
Now this guide is about fishing in “Pure Waters”. These spawn in different places around Nagrand and each time you can get quite a few Motes of Waters averaging around 6 motes per Pure Water. The spawn spots for Pure Waters are all around Skysong Lake (next to Throne of the Elementals) and Lake Sunspring (next to Sunspring Post).

Now just fish here for as long as you want, the trick is to find the spawns before anyone else, that’s why I recommend you have an epic flying mount instead of a regular.
I average around 18 Primals an hour and I have once even gotten 20! This goes to show how much gold this guide can give you.
Have fun fishing
