I know that he had an acclaimed role on Thor but I was surprised to learn that it was only 4 years from 1983-87. Much shorter than Peter David on Incredible Hulk. I'm curious, why? Did he leave the book voluntarily? Did the EIC push him off? I'm surprised that he didn't stay on longer considering. My other question is, how did the Thor mythos change from after he was on the book compared to Lee/Kirby and other writers before him?
