I'm still new to lvl 50 crafting, and made a pair of Botanist's Gloves for my new lvl 50 BTN. At first I thought that the two Control numbers (something like Control: 255 Control: 315) under characteristics were the requirements for NQ and HQ respectively, but I ended up making HQ gloves at 280~, so it seems that isn't the case. What do the numbers refer to?
