I always stay a Warden with him, but also I think it might help if you know whether you're going to harden or soften him. I always feel too guilty to make him king when he's softened. And yeah, I can imagine how different Orzammar stuff is when playing as castless, so I'm excited to eventually get around to doing it.
I'm also looking forward to what I'll be doing;;;; I have no idea, but I'll figure it out! Hopefully. And I'm interested in seeing what you end up making!
