I actually made a thread in general about this, because the whole thing annoys the hell out of me. I'll paste it here too:
I'm here with an issue regarding crafted gear. I have blacksmithing, so obviously that means that I can create epics weapons and armour. However the material cost for these items seems a little ridiculous considering the ilevel of them.
For example, I want to create Lionheart Executioner, Reborn. To create this, all in all I need 18 living steel. Living steel goes for around 500g each on my realm, so that's 9000g. Or I could find an alchemist, and get them to let me use their cooldown for 19 days. All to create an ilvl 502 weapon. Or I could just run LFR and get one for free.
Same thing for armour. I could craft something like Haunted Steel Treads. These require 6 haunting spirits. These go for around 16k each. So that's 96000g, all for a set of ilvl 522 boots. Seems a little excessive, no?
So my suggestion is this: either lower the material costs, or increase the ilvl of these items, to make them seem actually worth the effort. Because at the moment they're just not.
In addition, I don't particularly like how enchanters and alchemists seem to have a monopoly on materials. If I want to craft anything with a high ilvl, I need the assistance of either an alchemist or an enchanter. However as far as I can tell, they don't need my assistance to create high end things. Enchanters don't even need rods anymore.
I can create one high level crafting material: lightning steel. However, this is BoP, so I can't sell it, for example to make some money to buy haunting spirits.
So my suggestion: change lightning steel so it's not BoP, and make it required by some other professions, to balance things out. And I'm not just talking about blacksmithing, I'm sure leatherworkers and engineers need enchanters and alchemists too. I don't think it's fair that they have the monopoly on essential materials.
