Shall I Switch?

Currently I'm a 375 Enchanter/Tailor. I picked them initially because they offered the greatest bonus to me as a mage. I could enchant my rings and I could tailor the Spellfire set. As we go into Wrath, I hear more and more about how there won't be as many reasons to continue with the professions I've chosen. Almost all high-level items made via crafting will be Bind on Equip (BoE) in Wrath. So no more Spellfire sets, no more high-end blacksmithing weapons. Instead, each profession gets it's own little perks.

Blacksmiths can add sockets, leatherworkers get furs for their bracers, tailors get embroiders for their cloaks, enchanters keep ring enchants, scribes get shoulder enchants better than the faction enchants, alchemists get increased effect and durtion from flasks and elixirs, jewelcrafters get BoPickup gems and trinkets, and engineers get their own aresenal of fun. (Most of this was culled from this great WowInsider Post)

Now, to break it down for me, as a mage.

Blacksmithing - add two sockets, one to bracers, one to gloves. Socket with 2xRuned Scarlet Ruby = +38 spell power.

Leatherworking - add "fur" to bracers. Add Fur Lining - Spell Power = +67 spell power. Minus out a bracer enchant = +37 spell power.

Tailoring - Early theorycrafting puts the gained DPS at about 24.4 for Lightweave Embroidery. And you have to give up a nice cloak enchant such as Greater Speed. As of now, this profession seems to be the weakest.

Incription - Enchanting the shoulders with Master's Inscription of the Storm adds 61 spellpower and 15 crit. Subtracting out Greater Inscription of the Storm, we get a net gain of +37 spell power.

Alchemists get increased effect and duration of flasks and elixirs along with Mercurial Alchemist Stone, +50 haste, +59 spell power, +40% effect from potions (however, you lose a trinket spot, so net effect is yet to be seen) - it is quite powerful when you hit level 75 though.

Jewelcrafters get their BoP gems and trinkets. Three Runed Dragon's Eyes gives you three +13 (after subtracting out rare quality gems), or +36 spell power (plus BoP trinkets - like this sweet Twilight Serpent, which not only increases hit by a great amount, but it has an on use effect and two sockets, which have a bonus of +7 spellpower. Not too shabby.

Engineering gets their sweet Visage Liquification Goggles which have consistently been upgradeable to the latest tier equivalent in Burning Crusade via v2 or v3. These liquification goggles are amazing and probably wouldn't go out of style for a long time and would probably only be replaced if there were a tier set that surpassed it with set bonuses.

So right now, I'm seriously considering dropping Tailoring and leveling Engineering. I won't miss the cloak enchant as I am currently in love with haste and while not having a flying carpet will be tough to deal with, I will be able to craft an amazing pair of goggles and my own flying and riding vehicles. Add to that the availability of another pet that has eluded me thus far, and I'd be sitting pretty. It'll be very tough to drop tailoring after all that I've spent on rare recipes, but I feel that Engineering will be more beneficial to me in Wrath and now is the time to start working on it.
