This fellow is a Blacksmith, and just recently reaching 90 I finally found out that living steel comes from alchemy transmutations.
Now, I have a mage alchemist, but I haven't touched that character since Cata so he is still lvl 85 with 525 alchemy. My first thought was to run that character up to 90.
However, I thought it might be beneficial to raise it on this character. While it may be silly to raise a second alchemist it would save me from going through Pandaria questing again, and I wouldn't have to switch between characters for a BS/Alchemist combo. Not to mention the double perk of having two primary professions on one character.
So any input? Should I drop cash and level alchemy on this guy? Or should I get over the drudgery of a second quest grind and get my previous main to 90?
