We play the Weekly Heroic to get a reward . We went through enemies to eventually get some reward , but the reward is unknown , even if it is RNG , we play missions for the RNG to give a reward . So yes , we do work for items , Xür? Yes we work for the items he sells to . Weekly Heroic is not RNG , it promises you Strange coins if completed .But if RNG was constantly dropping items , even while in the tower or every 10 seconds something drops , then yes we wouldn't work for anything
