This is a WoW Gold Guide on Motes to Primals.
Ok, I admit that this isn’t a really good guide.. But I sometimes find that you can get 10 motes of the same type for a lot less than the price of 1 primal. This is what you can do:
- Jot down the price of all the Primals in the AH (eg. Primal Shadow)
- Check the price of the mote needed to make the Primal (eg. Mote of Fire)
- If it’s significantly cheaper, buy them
Most people sell the motes only because they don’t know how to turn them into Primals. By just checking WoW Head, the average buyout for one Mote of Shadow is 2g 50s; the average buyout of one Primal Shadow is 30g. It’s a quick way to make money I guess 
Tip: You could also try transmuting Primals from one that is cheap on your server to one that is expensive.
