Don't get your hopes high is all I will say. Oda is very good in causing disappointment especially where this is shanks's first relevant on screen fight. Kidd will do something decent but keep your expectations to minimum otherwise you will be left disappointed.
Aye man, you're right. Oda made that abundantly clear for us last arc and even in this arc too.
There's a big fear for me that Kidd and Law will be hype tools for Shanks and Blackbeard, to get them poneglyph copies and w/e else and make able to directly challenge Luffy more "equally" for the One Piece and not need his copies. To get them much closer to it without relying on him.
Oda giveth with letting Kidd and Law take down Big Mom but he may taketh away too by sacrificing them for BB and Shanks greater roles/importance/relevancy etc.
I'm a huge fan of all 4 too do this is very ironically conflicting for me.
I guess these kind of clashes and situations with them were inevitable too tbf.
Going by what you said too ofc, how important Shanks is to Luffy too, how Blackbeard can eat 2 DFs, Shanks true fighting style, Awakening of Yami at least, Shanks implied nobility (From Film Red) etc and even Shanks and BB lifelong history vs each other are far too important to be wasted too.
It's good advice anyways man tyvm. Kaido deserved much better too but alas.
