lol if King has advCoC then I would also put King one level above Queen.
But the representation of them being posed directly as equally difficult obstacles over and over again, being a pair, rivaling each other and having an almost equal reward is something too clear for us to ignore.
Ah, cheers. If you're willing to put King level about narratively and portrayal-wise if he shows skillset to match, then it's alright.
And yeah, I'm not ignoring it, just saying that Oda can decide to increase and decrease the gap to his liking as they both get individual their portrayals. So far, King and Queen have been presented in pair, but their combat portrayal have been more about generalization of a minimum level rather than direct comparions.
"Two pirates above 1 billion" is a generalization of above a billion.,
"Neither the routes will be easy." is a generalization of two characters who are both capable of stalling just fine, making it not easy at all to lol go through.
But yeah, until their individual portrayal and VC, the narrative was pretty similar regarding both.
