Hey,
I’d like to suggest to revisit crafting costs for items of those 2 expansions in terms of the usage of the certain elements needed to craft decor.
It seem a bit odd that Primal Fire/Eternal Fire usage is almost 8x higher compared to the other elements, whilst Cata manages almost an equal distribution (granted those elements are easier to grind but still).
The latest additions to the PTR pool of crafted items further increased those numbers.
Slight readjustments to the numbers might help to even it out a bit!
