This a thousand times over. All the greats knew way more than just having comics knowledge. They used that broader understanding and absorption of wide varieties of media to enhance both their art AND their writing
my hot take is some of y'all need to stop only reading comics. read prose, go to a museum, learn scrimshaw, wtfever. go be an interesting person first because i can TELL when people don't ingest anythiinnggg else but comics
