If I'm talking about you, you justify your blinded fanaticism with "if oda wants".
If oda wants too Nami is r1 in the verse.
Not at all ,Oda does keep power scaling in mind which is why nami need help vs ulti and ussop lost .
Oda has power scale luffy into the top tier with his fight with kaido and giving him 3 power ups ( the most luffy ever get at one time ) since we near end of the manga .
The most luffy has is 2 big fight and that it , the man want finish in 3 years .
Luffy can still lose but he also in tier where can win and it make no sense saying he can't beat a or b or c now that we at the end.
