All of this goes to show again that you can really categorize Oda's way of handling fights & scuffles into filler fluff and real climax fights.
The HK fights were still lvl up filler, even if already pretty good, similar to fully braindead Goofy and base Loki putting in work against Imu.
The real stuff will happen from 1199 onwards. When you have hybrid Loki, the powered up wings and incoming powered up Luffy all at the Imu front.
I expect 3-4 10/10 vs Imu chapters with some Ussop and Biblo box stuff inbetween.
