So the mystic forge, when you combine 4 items of the same they should output the same item. I’ve tried putting 4 green medium shoulder pads together and it always gives me a light back. light green, light yellow. I believe it might be the same for heavy and light. Now it seems when you put in something of different armor values, light heavy or medium, it considers it random. Like if i put in 2 light shoulders and 2 heavy, it considers it random and will give me a random armor piece. So i believe that it is supposed to be outputting medium shoulders, and it is not.
