As the next expansion approaches, I find myself thinking more and more about the crafting choices I've made and the new profession we'll be gaining with Wrath of the Lich King. Obviously as a commentator, I'm obligated to try Inscription and post my findings, that's a given. However, I currently have 4 level 70 characters and they are spread pretty thin (Skinning/LW) (Engie/Chanter) (Smith/Herber) (JC/Miner). I also have a 62 who's my Alchemist and could potentially be a Tailor if I decide to actually play him.
Aside from the issue of covering all the bases on my toons, there's also the dilemma of which one should take up which craft. I find myself quite annoyed with Leatherworking at the moment because once you've cleared Karazhan, there's no reason to keep making yourself BoP items as a Resto druid. They did just add some new patterns to the Sunwell, but most of us will never see that so I have a hard time counting it as a legitimate gear upgrade path. As it stands, my Leatherworking is predominantly providing cheap leg armor to my other toons. Kaliope actually makes better money from fishing than she does from Leatherworking, a pretty sad state of affairs to my mind.
While I have serious doubts about the benefits Kaliope gets from Leatherworking, you could argue that my rogue would benefit more from all the crafted DPS gear. I know there are other folks who will actually level a tradeskill from scratch just to get BoP crafted items such as the Primal Mooncloth set for healers or the Weaponsmith epics for melee classes. How many of you choose your profession based on the BoP epics? I know right now I have a hard time dropping professions because most of mine have been in place since 1.x and I don't want to spend a mountain of gold to retrain into something else and lose all the recipes I currently have. In some ways I'm rather hemmed in by the choices I made 1-2 years ago when none of the current end-game options existed. In other ways it has been very handy to have older recipes so I can share crafted items with others who need them for leveling.
Another consideration for what craft to take is the end-game itself. If some of your toons will never see Karazhan or SSC or the other high-end instances, you can't select a craft that depends on those BoP and/or faction recipes no matter how nifty the item might be for that toon. I know I feel like I need to keep my rogue a Jewelcrafter because she's actually geared enough to take on raids. In this way my druid is once again wasted, because her leatherworking doesn't gain her much in the recipe acquisition department. Overall, it's getting quite complicated to choose the optimal profession for each toon. So how do you guys make a decision on what tradeskills to take and how often do you switch if you change your mind? I'm curious what process other players use to make such an expensive decision.
