I have had 9 missives I believe. And I have only ever seen thorn, bad juju, invective. Is it normal to only get the same three? Is the mentor missive decided on the three bounties when you pick it up or can they change after awhile? I have had thorn invective and bad juju three times each. I would really like to know if I'm stuck with these three bounties. Edit: answer is no, thanks all. I have really bad luck with these then>.<
