I wanted a few Y1 items in the form of Armor2.0. What did I do? I went to a planetary vendor of my choice and kept pressing one button for several minutes until I ran out of materials. Haven't gotten what I needed, so I went to Spider and kept pressing one button for several minutes to buy more materials. Rinse and repeat. So, mindlessly pressing one button in the menu IS a legitimate way to grind for random rolls. Why the middlemen? Why can't I do the same right from my collection? Adjust the costs and here we go.
