Honestly I'm fine with not seeing PH, I just wish we got to see more of Kizaru vs Luffy and Kuzan vs Garp's offscreen bits in detail.
The whole reason Luffy got tired against Kizaru in round one was because Kizaru and he were fighting hand to hand offscreen, and we didn't see any of that.
It's actually annoying. The whole idea of Admirals having non-DF skills is so cool, but there's barely any elaboration on how that works.
It's impossible to tell if Kizaru is even using advanced haki in EH. It's also kinda weird how despite training Sento he never shows offensive moves with barrier haki similar to Ashigara Dokkoi.
