Yup. In one day I got two hard lights. One from an engram, the other from crucible. I also get patience and time frequently I got one from engram one from crucible and one from Deathsinger. I don't believe you get assigned certain exotics, just that you are assigned to get ones more often, I still think you can get every exotic RNG. I didn't buy suros and was mad and then finally got one on Deathsinger. Now with exotic bountys I get one just about every day.
