I can see his point, and I believe it is valid for a great many professions. It is difficult to make money on a few crafted epics when all blacksmiths can make them and the mats you have to buy mean you're taking on a lot of deflationary risk. Tailors and leather workers certainly have similar gripes. Really, I believe Blizz needs to make some rather large changes to their professions so that people don't feel like they HAVE to have certain professions to have a shot at making real money. Why should jewelcrafting and enchanting get all the action if someone doesn't want to spend countless hours in a gathering profession? For example, enacting the following changes together would make more of the professions more equally relevant compared to each other:

Take the head and shoulder enhancement slots that for most people currently come from some faction rep, plus add a neck enhancement slot, and make those 3 all crafted by tailors.

Add slot enhancements to the trinkets, as in, say, trinket pouches, and have those pouches crafted by leather workers. Add a slot enhancement to thrown/relic/wand such as a sheath, again crafted by leather workers. That adds 3 enchancement slots to what leather workers can make.

Take prospecting and move it over to blacksmiths. It makes more logical sense anyways that miners bring rocks (ore) to a blacksmith who crushes/processes it to find the uncut gems, but then can't do anything with them himself and requires a jewelcrafter to actually cut them. Also take gem transmuting away from alchemists (I am one!) and give it to blacksmiths with a new name. This way blacksmiths become the suppliers of uncut gems.

To compensate alchemists, who I think are currently balanced, for the loss of gem transmutes, make potions elixirs and flasks more powerful so that people really will feel like they have to use them to actually do well. Make all elixirs last through death like flasks do now, and just decide that elixirs are the cheap version of flasks.

Anyways, you get the idea. The ongoing item enhancement markets are really the only lucrative non-gathering professions right now, in terms of time spent and cooldowns and restrictions. I know because without even trying very much I made 120k in 1 week with my enchanter/jewelcrafter when patch 4.1 came out. Even now, with an hour a day I can still make a few thousand a day with them. It is time to give all crafting professions a more equal slice of the item enhancement pie.
