So, I've been trying to get the Imago Loop. The only way (that I know of) is to do the Undying Mind or Echo Chamber. However, getting a Vex strike is EXTREMELY hard to get, and I don't know why. Out of 15 strikes that I've loaded into NONE have been Vex. At some point I got Taniks three times. Please fix this issue Bungie. There's almost no diversity here Moving on to my second thing, there is a glitch in the Echo Chamber that doesn't allow you to get the Skeleton Chest. After you kill the boss there is an invisible wall between you and the chest. Please look into this Bungie
