I am a bs375 specialist swordsmith..I have made FIREGUARD and LIONHEART swords...Both swordsmith specific..If I now unlearn Swordsmithing and change to Armoursmithing will I lose the ability to use these weapons

Just as you have to be 70 to wield it you must be a swordsmith

gee, and lvl'ing up to be able to make a weapon or piece of armor, getting all the mats to make it? that is NOT good enough to use it? i honestly refuse to craft anything anymore, crafting is simply a time and gold sink. You spend thousands of gold to get to 375 then cant make anything unless you run many many heroic instances to get one item out of a huge list of mats to make one item, yes that item is sweet, but after running that many heroics... wouldnt you have at least one awsome epic? yep, im dropping them all and just double gathering. Not a newb here either, been here since beta, just real slow in thinking mabe blizz would make it worth crafting, after all these years i just give up...

Funny...most people I talk to say the BoP epics with crafting requirements to equip are the only things that really make their craft worthwhile to skill up. Engineers, Blacksmiths, Leatherworkers in particular. I know a lot of Alchemists make their gold from the sale of high-end consumables (esp. when they get specialty procs that produce more than the common result), but for the other production professions, they're quite happy with the things they are able to produce for themselves.

I'm leveling Leatherworking/Skinning on my new Tauren rawrkitty as I work my way up the ranks and I'm pretty much breaking even at this point. I recognize that the final push will get costly, but considering most people pair a gathering profession to the production profession of their choosing, you can be a bonehead and buy your mats out of impatience or you can go out and gather the mats you need while your gold reserves remain steady. Primal Nether as easy as sin to come by by the time you really start needing them. If you don't want to wait until they're a fairly common commodity, you fall into the same category as folks who want to be hand-held through the attunement process for Kara so they can start raiding in their Nagrand quested greens/blues.

I don't know why I'm still armorsmithing as a pally. Hoping that something good will come out after spending countless hours grinding for thorium. I don't think I've used any of the items I crafted for myself. I've had guildies request certain items for their low-lvl alts, but nothing appealling on my 70 pally.
