Although not a TRUE bug I do personally think that the massive price difference between the professions needs to be fixed.
(prices at time of posting)
To buy just the leather alone costs around 52g, not too much.
Next is the Deldrimor Steel, ranking in at 106g, getting a little silly here.
Finally we have the most appalling, Damask coming in at a whopping 202g.
Can the recipe’s please be fixed to have an equal cost to all professions or better yet just pick one recipe and go with it. In my opinion it’s a bug if a light armour character is thinking about lvl 500 leatherworking because it’s cheaper.
