Yeah, I'm not specifically disagreeing with it myself. Like I said, to each his own - I understand quite well what he's saying and agree with it to a point. The only real part I'm arguing with is the generalization that a character with traits equal or similar to your own can't be roleplayed.
Also, as a PS on the topic of old characters, Jigain To'lerean was the name of the very first character in the very first story I began writing.
As I am wont to do, however, I never finished it. I will, at some point... but probably not until I have kids who want to hear a bedtime story.
