No foreshadowing indeed because none needed, it would have ruined the revelation, but like I explained in the thread there were at least 10 shadowings, which are - if you understand what I wrote - essential to make the revelation cohesive and acceptable (to those who actually pay attention to the shadowings of course). Those are the way Luffy fight and the nature (physical and fighting) of the transformations.
I don't need to read your analysis to make sense of the story.
Do I believe nika was foreshadowed? Yes
Do I like G5? To some extent yes
Do I think Oda deliberately hold df reveal to be surprise element? Perhaps
Does it make WG looks like clown? Yes because they had info yet they didn't do shit about it until oda was about to drop luffy awakening
Was execution top notch? Certainly not and I definitely understand why some people are upset about it.
I don't need to blindly wank something and try to superimpose my opinion on others just to call others haters for expressing their dislike. More so when many people who are arguing against this happens to be Luffy fans or like other Gears .
Likeness is subjective and everyone has different taste.
