Everyone can craft everything, and that is IMO a big problem in this game if you want to actually make money out of crafting.
Just look at the AH, i recently bought a cryotech alchemer for 1800 crowns, where the energy-only cost of such an item is already 2800cr as we speak (and that doesn't include the 400cr crafting price, nor the mats, nor the 10% AH fee). How could I get such a bargain? Well by the laws of market, because the supply exceeds the demand by far. I'm not complaining about making a bargain, but merely pointing out that you can't make money from crafting, the reason being: why would someone pay more than the crafting price of an item when he can do it himself (of course there are idiots around, but this game is not about being an idiot is it?).
Currently I only see 2 good reasons to even begin bothering with crafting:
1) because you need lvl 5 gear to upgrade to 4* (thus requiring to unbind if you want to buy the thing at the AH)
2) for the chance of UV (but let's face it, 10% chance to get a UV that will be nearly useless 90% of the time isn't really an amazing prospect)
No, crafting needs a change, needs to be really attractive, needs to be a win-win for both the seller and the buyer.
What change? well most MMO have sorted that out: professions. Make it either very specialized (swordsmith, gunsmith, bombsmith, armorsmith, shieldsmith, trinketsmith), just a bit specialized (weaponsmith, armorsmith) or something in between (primary and secondary profession)
that would certainly not be to the liking of many people, but it would make the AH more useful in this game where currently it is only a way to rip people off by getting outrageous bargains.
i dont like the idea of limiting what i can or cannot make
