I had LW & skinning up until 70, and usually had a few things I had made equipped, as well as some sideline profit to be made from getting someone else to DE the stuff I made as well as selling it.
But I quit that at 70. Why? The 300+ LWing just didn't, for the most part, seem worth it. Sure, the riding crop and clefthoof/cobrahide leg armours make it more than worthwhile if you're using them yourself, but the prices to sell them were not really worth the time spent farming the mats or even AHing them. And the epic leg armours are no real improvement over the first set to keep my interest. And the elemental set you can make at 375? Bah.
So I'm now a miner/jewelcrafter, moreso as my guild didn't have a 300+ JC and we were getting rinsed in the AH for gems. I still have my qualms, but at least I have a profession now that I can advertise over trade. Even made myself a little office out of one of the empty shops in Stormwind - not so much an office, as I just stand there!
