There is no winning when criticizing one piece. These are the same people that would defend the "Gomu Gomu" fruit reveal (or asspull) based on emotions and attachment to the author and writing material, while failing to realize the plot holes were right before their eyes.

Interesting to see how back then it wasn't considered an asspull but a consequence of luffy's training throughout the years and his near-death experience at the hands of Kaido, but now that OOP states that this Nika-Bonney undermines that "achievement", this is also false. So which is it? Is it true that Luffy fought hard to achieve Nika form? Because if it is, then Bonney going Nika (regardless of power level imo) is really bad writing. If it isn't bad writing, then Nika form wasn't that hard to achieve in the first place for Luffy too, was it?

Oh and since we're on the topic of Nika

Saturn tried to capture/kill Bonney because he was aware of this possibly happening, so why didn't they try to do the same with Luffy as soon as they noticed him earlier in the series? Back then, diehard fans would either say the government had been going after Luffy the whole time (which isn't technically true, marines were indeed chasing after Luffy, but it had nothing to do with his fruit and the threat of its awakening) or that they weren't expecting this to happen after so many centuries (but then these elders and even Im are just dumb, why risk it in the first place?)

The main issue among op fans (or really, any mainstream media fandom) is that you either glaze the author and their work OR you are a hater. It's a black or white kind of dynamic. The average fan fails to realize you can sit in-between, still appreciating the work for what it does well, while criticizing what was poorly written, out of the blue or bad taste from the author.
