Can you maybe explain why? As others have pointed out in my trio thread, she is in more keypoints of the story as Sanji
E.g when meeting BB
Pre-TSPre-TS, Nami was definitely more relevant. But then again, back then Nami was tagged with Luffy and Zoro (hence the OG trio). Example,
Whisky Peak, Jaya, when Luffy came to take back to fight Enel, and Water 7 Aqua Lagna.
Can you tell me such team ups in post-TS? I can remember only two occasions - Luffy teaming up with Law and Luffy/Nami fighting Cracker. Everyone would agree that Nami's best post-TS moments came in WCI and that was an arc of Sanji, Sanji clearly overshadowed her there.
So, how am I supposed to take her as important figure just because of one panel with BB?
Don't get me wrong, I am a fan of Nami and very much like the OG trio (my UN is basically Zoro 11, Luffy 56, Nami 73). But Sanji has replaced Nami in terms of importance.
