two things, mildly useless
1. 
Draw your own conclusions, because I sure as hell don't know what mine are yet.
2. I have a steadily more burning desire to write Highlander fic. Goddammit. At least Doctor Who has cured me of my conviction that I need to have a comprehensive knowledge of the canon before I write in the universe? I'm still pretty sure, though, that by "write Highlander fic" I mean "write hilarious fic about how Methos is four millennia older than the Doctor, so there." I don't even know, guys.

Re: magical immortals, I was slightly tempted to tick 'magical' next to the Doctor, but that's sort of stretching it, and yes, I think as character traits they'd tend to become overpowerful very, very quickly.
