How do people feel, especially RPers, about having Frea as a companion? I'm having second thoughts, as she is meant to become the Skaal shaman after Herma-Mora decides that impaling Storn would be a fun thing to do. Meaning that, if she is with the player, then the Skaal have no shaman. Of course, this will have no impact on the game itself, but it's a bit of a problem in the RP department for me, which is a shame as Frea is brilliant in Miraak's temple.
Also, I read on UESP that she has unique dialogue for some quests. Does this refer only to quests on Solstheim, or quests back on the mainland as well?

I thought she was a bit naive, but she had nice Lightning powers.
