Oda's way too lazy, well out of his prime at this point it's obvious. Like OP said, Luffy bodied Blueno but that was a masterpiece.
I remember he admitted to this in an interview a few years back broken down by Sandman I believe:
"ONE PIECE has more characters than before. He has to cram much information into one chapter to move forward with the story. Oda says he would be able to draw really impressive fight scenes only if he could keep drawing the fight scene for 2 chapters in a row. He feels ONE PIECE can now spend only 1 chapter at most on a fight scene."
Issue is he'd rather draw a whole bunch of nothing instead.

Even then... I expected atleast something from this fight. Some piece of cool choreography like Bird Dance vs King. In the end, i guess Oda is just growing more & more senile as you said.
