I’ve been trying to get an answer about this for a while; a Blue post would be awesome. It has to do with the cost of training any of the Classic professions. I’ve been trying to find out if this incongruity is a glitch/error or done on purpose?
So, same as anyone, when I open my Profession Window I can look at unlearned recipes and hover over the ‘i’ info icon and it will show me what it costs to train that recipe. However, when I go to the trainer, the cost listed is anywhere up to 550% more. Keep in mind, I’m at ‘Revered’ reputation with the faction of the profession trainer.
I took some screen shots of four recipes, where I compared the price listed in my Profession Window to the price listed in the Trainer Window. I’ve seen this discrepancy at multiple trainers in multiple locations for all the Classic professions, not just Blacksmithing. Take a look at these screen shots for yourself: (I don’t believe I can post imbedded images, so feel free to copy and paste these links)
