If I remember correctly, in the future the HQ crafting system will be symplified to
HQ + HQ + HQ material = HQ item, but I can't seem to find in what future patch that system is supposed to be implemented. I have quite a number of HQ mats saved for my crafts and am wondering if I should be holding off upgrading and melding gear if there is further benefit to be gained from HQ gears that would be easier to make in the future.
