I know that when Classic X-Men was being released, they added new pages to the original material. I know there was a story that had to change how a scene worked because it was originally inconsistent with how Nightcrawler's powers worked. Does anyone know which stories had changes to the story?
Also, I recently read Claremont's Ms. Marvel. Combined with my reading of Claremont's Iron Fist, it made me realize that it might be fun to re-read Claremont's early X-Men in the context of those stories as well. I've previously read all these stories. On the re-read, should I read the Classic X-Men version or the original?
