He does need some more items to sell. I would like if he sold one Legendary Weapon and Armor piece of a select set each week. Like have monthly dedication. Month one could be Dreaming City. He would always sell the Class item, then have one other piece and a weapon of that area too. Maybe make it 20 shards each. After 4 weeks he switches planets/areas. But he sells them max 575. (Scales with player level like currently does)
