Yes re rolling at gunsmith is making him useful until Taken King but we run out of weapon parts and glimmer too fast until we get our perfect roll. Im more than sure that a lot of us have over 100 motes of light and i would like to have the mechanic of lord Saladin rerolling weapons for motes of light. Instead of the original price of 1, make it like 5-10. I don't know what you the community think but me as a year one player with literally 2 weapon parts and 1300 glimmer is a horrible feeling and discouragement to continue playing the game until Taken King DLC.
