I have spent at least 15 hours if not more killing wizards and knights in the dreadnaught, and have not gotten a single wormsinger rune. I thought it is supposed to be a common drop I demand an answer from Bungie immediately. What m I doing wrong is my light level too high or low, am I killing them with the wrong weapon, am I not killing them correctly, is there a specific place and time in the dreadnaught to kill them to get the rune. This is an injustice that many players are dealing with. Bungie either fix it or shut the game own and refund everyone's money for wasting our time
