I'm a pve mage, but Tailoring seems to have lost its appeal to me. Crafted items are garbage for a fire mage and they go really cheap on my realm, really not worth the Imperial Silk. I was thinking of changing Tailoring with Alchemy, since it is a good profession and it will save me a lot of flasks when raiding. The question is, is the increased flask effect from Alchemy (+320 intellect) equal to Lightweave embroidery in terms of dps? If anyone knows the math, I would be grateful
