Simone wanted to use the Greek Gods from Rucka's run and was vetoed the idea by the editor who iirc is the same person that helped sabotage Waid's run of Captain America back when he worked at Marvel (and also burned through close to 10 different writers on the two Superman books in the span of five years). Though to be fair he is also the credited for the Azzarello run, but that one had several powerful people including Didio and Chiarello backing it.
