My honest reaction is an oversell lol? I'm telling you my expectations from Kuzan and GB were that Admirals can obviously tank advCoC and bounce back, no problem, we've already seen it. So Kizaru going toe to toe with advCoC Luffy wouldn't be that big a deal for me. That's why I thought Luffy for sure was using advCoC, because I thought Kizaru actually took damage.
What I did not expect is for Snakeman + FS to be unable to land a single clean hit on Kizaru. That is out of the ordinary in my book.
