Arcane Brilliance: Professions for Mages, the thrilling conclusion

Each week Arcane Brilliance brings you a column about Mages and all things Mage-related. That's right, Arcane Brilliance is nothing if not consistent. You won't find any server instability here. We're never down, we're always up, and you can always enter our instanced content. And the best part? Arcane Brilliance doesn't charge you 15 bucks a month. Although, donations are totally welcome.
So how's everything? Did you make it through patch day unscathed? Did you log in, like me, and find that your Mage's face, forearms, and feet were gone, and there was a hole through his chest (pro tip: upgrade your video card drivers more than once every three years)? Are you running out of mana at an outrageous clip? Are your crit numbers from Molten Armor up or down? Did your guild manage to make it into Ulduar yet, and if so, did you manage to snag any phat loot? Did you dual spec your Mage so he can now both DPS and DPS? I went Frostfire/Firefrost, myself. When triple-specs hit, I'm taking a Frarcano-fire spec. Mark my words.
All in all, I'd say 3.1 wasn't too bad. We have some new glyphs to play with, the Argent Tournament is good, clean fun, our mounts can swim, and we have a whole new batch of loot-pinatas to blow up. Our DPS seems to be down a bit, but we're still beating Warlocks, so I'm not going to mail any angry, expletive-laced letters to Blizzard just yet. I've written them--rest assured--but I'm not yet prepared to actually invest in stamps for them. Those things are like a buck apiece these days.
So now we turn to the third and final installment in our guide to professions for Mages. If you missed them, the first two parts can be found here and here. This week we'll investigate the merits of Blacksmithing, Leatherworking, and Engineering. As an added bonus, we'll take a quick peek at the three secondary professions and enumerate the reasons for investing in them. Yes, even though you can conjure Strudel from the very air around you with but a word and a snap of your fingers, you still need to learn how to cook
