JC cap: Draenei racial is a burden, not a bonus.

The cost is exactly the same whether you mine the ore yourself and prospect the gems, or you buy them on the AH. You could have sold those uncommon gems on the AH, and that's the cost of opportunity involved.

But instead of having 500 less gold than you did before, you still have the same amount, rather than 500 less. If you are low on gold, keeping it even by farming your own mats is the best choice.

OT: Your 525-535=515-525 for all of us. It isn't a burden if you know how the profession skill bonuses work.
