At the moment, there is a serious discrepancy between how easy it is to obtain the various trait mats for Jewelry Crafting. To make triune, you just need to buy the mat, whereas to make infused, you have to grind a farming route where the chance of a rift is on a par with pre-change chance of getting pewter etc. I found five in a couple of hours of grinding yesterday. In very few of those rifts is the base material. You then need to be lucky enough to find rifts, and lucky enough to have a rift drop the mat, 9 more times before you have enough to refine one infused trait mat.

The grind to level Jewelry Crafting levels seems mostly balanced in terms of number of items to decon, and the logic for the insane grind to get plating mats makes sense to me as a method for delaying how fast people max out the skill. But to add this level of RNG to a simple trait mat seems insane. This is insanity is then added to by the fact that the RNG is worse for some traits than others.
