That’s what Brubaker did lol. Johns probably blocked Gail on Billy & co. but Didio was the one who blocked Waid on Supes. Waid also got blocked because of the Superman 2000 pitch that caused him, Morrison, Millar, and Peyer to get banned from ever touching the Superbooks by Carlin (which only went away when Carlin left and Didio asked Morrison to write Action).
