This has been bothering me since beta... Does anyone ever risk using fewer than max upgrade materials when improving a crafted item? I personally never risk losing all the resources that go into an item to "save" a few mats (esp with ESO's RNG) - doing so is a guaranteed statistical loss over time. For me it's just a useless "knob" I have to remember to turn every time I enter the crafting improvement UI. Am I missing something? (Also, is there an add-on to set it automatically?)
