I should add for textures that the exceptions though are already high value textures. QR 1 praetonium is still bouncing around 100-150 ped last I checked, so QR 100 is uncharted territory. For high cost clicks like Molten Red Crystal, I would have paid 500 easy in the past back when MU was high because I already lost a couple hundred ped crafting those textures just for one texture project.
Overall, I’d try to split them into three groups. 1. Junk, 2. Useful for texturing or skilling, 3. High value textures or high ROI on QR (i.e., costly to raise QR).
