Gamma knife being a super effective against BM or Kaido would leave a really bad look on the story I think no matter how many times ones explain that Doffy resisted its effect cuz his DF.
I blame Oda for using such move so early and diminish his impact.
(Law beating Doffy with Gamma knife would have been better tbh story wise but Luffy needed the W I guess..)
Oda should have sent Kuma as a complete weapon on Dressrosa
And should have built up both "Kuma and Mingo" as same level and written them that way, by also demonstrating that Kuma did not lose strength when he turned into PX0
Thus, Doffy pressuring WG and pulling strings, results in having 2 warlords as enemies
AND then Oda should have made it completely IMPOSSIBLE to get back Kuma because he's completely dead, no way to return to his former self
Thus, building a sentimental battle, which will be very emotional fight for Luffy because Kuma helped them a LOT!
Law against Doffy is very impactful as well!
Then,
Law beats Doffy himself
Luffy beats Kuma himself
Resulting in Law staying in circle of rivals...
But instead Oda sent Fujitora just to be a spectator Doing NOTHING noteworthy, a freaking admiral having no impact on an arc
Doffy, Law's personal grudge for 13 years, is defeated by Luffy, and Law used every single shit in his arsenal against him leaving him with no tricks, and Doffy didn't even bother to use awakening on him
In fact, Doffy barely used Haki hardening against him, it was only seen in 1-2 scenes at best
Oda completely destroyed any hope for Law to be a future rival
To the point that honestly, his role is very supportive at best with Luffy
The idea of Luffy taking out the personal grudge of his own rival just sealed it for me!
It's like for example, Zoro trains for Mihawk all his life, then at EoS, we have Zoro loses to Mihawk
So Luffy says "okay, I will beat him for you, no worries"
Lol, Luffy did that for a supposed "rival" of PK throne
Thus made Law immediately withdraw from the race of PK throne in my book
And I fear the same for Kidd this arc Lmao
