I've put my professions on the backburner for now. A lot of internet resources haven't caught up with updating all the new recipes, set items and efficient-leveling techniques for the new expansion yet. Plus my leveling plan for my characters is more focused. I'm going to level my druid Moneyball to 80 first and start planning my Naxx starter set. Since a lot of that is group focused, I'll be able to spend my free time working on alts and my profession empire. So it looks like:
Druid --> then (most likely) Mage/Rogue/DK concurrently (with an emphasis on the mage perhaps to get everyone good bags and since the mage is my cook/fisherman).
That said, I have leveled my druid's leatherworking slightly past 400, to keep my LW-bag uncongested if anything. LW is an easier profession to get the early points on, so it hasn't been time-consuming. But, Blizzard is on record as saying that they don't plan on making the early crafted gear from items as powerful as they were in TBC. This is a disincentive for me to farm, since I don't really like it and do it mostly for rewards.
So when it comes to capping LW, I'm going to compare the crafted gear to the pre and Naxx rewards, and if there is better gear I can get more easily than crafting then I may do that; and just get LW high enough for the drums I want and the bracer augmentations (I can already do fur lining at 400). If the crafting gear is on par then maybe I'll just stick with that, since soloing doesn't force you to rely on others (unless they're tagging your mobs). Once I cap or finish my major crafting assignments beyond things like future drums or fur linings, then I anticipate dropping skinning for enchanting. The ring enchants are great for healers and I'll always be able to DE in instances. The only other option is Blacksmithing for the extra sockets, but that seems kind of unusual to me to do.
I've also been storing necessary trade mats on the character who uses the profession. I might however take an alt, give it a "guild bank" and then use that character as a storehouse for all my wares. This way I can mail everything to one source, and then that source can parcel it out. Then I only need to buy bag space on one character instead of all of them, too. That said, there are some rather expensive vanity mounts in Wrath (the choppa! the elephant! flying mounts!) so I may play my cards close to the vest for the time being. Time to start brain-storming cutsey guild bank names. How about, the Nouns of the Modifiers But In Latin?
