I know you can farm raid exotics in the older raids, Kingsfall, for example. We did Vow of the Disciple over the weekend. None of us were sure if the boss checkpoint was farmable on the same character or if it was still 1 chance per character per week. Are all boss checkpoints farmable on the same character? (With the exception of Desert since it's the newest.) Or is it a mix of some farmable and some not?
