Great analysis until the admiral agenda at the end. Tho I'm biased enough to agree with you
Kuzan with the sentimental Garp nerf
Kizaru with the sentimental friends nerf
GB and Fuji with the holyland nerf
These aren't my opinions, but just what we've been told and shown in the manga.
Only Akainu and Aokiji have went all out, which is why they sailed to a far away remote island knowing they were not going to hold back. Only issue is it was offpanel in typical Oda fashion.
You would think by chapter 1122 in a series, where even the Yonkou have finally gone out a few hundred chapters ago, that Oda would let these dudes fight unrestricted, but nope. And the reason for that is simple, it would detract from what he is trying to draw, which is not fights.
