Also, I am going to buck the trend here and say I'd totally date Anders if I were a real person in Thedas. I wouldn't date someone with the equivalent mental problems here, but there being definitely and provably such a thing as Fade Spirits really colors all his problems in a different light for me.
Then again, this may be because I've never had a bad relationship, never had a bad breakup, pretty much just had affable, cordial affairs with completely stable cynics. I could use a big dramaflare to give me a story or two to tell. I could use some unrestrained passion rather than "I like you because you are smart and you don't seem evil. Why don't we date until we get bored of each other?"
If you can't stand the crazy, get out of the clinic. One side, practical, sane people!
