In preparation for the 3.2 patch I spent one month buying up ore from everyone/everywhere/everyday.
Purchased 700 +/- stacks for 105g each +/- total = 73,500g
Prospected 500 stacks using all the powder for tokens -> epic designs which made 90,000g +/- (Keep in mind I used the powders so this number would have been higher)
Sold 200 stacks for 225-250g +/- total = 45,000g-50,000g +/-
Walked away with rougly 66,500g +/-
