I think its VERY important to remind everyone that this conflict has only really been occurring for ~10 chapters at most. Take away the Kuma flashback, really not much has happened yet at all save for a few punches being lugged around between the Admiral and Gorosei. In the end, neither are still truly hurt or even down lol.
This is something I stressed repeatedly during Onigashima. Wait until some of the crew has their matchups, then you'll see real progress being made on who fights who and people getting injured.
When the crew arrives in Fabriophase, then you'll have your answers on what is happening with Kizaru and Saturn.
