you still had a ton of text in the marine ford arc with multiple character speaking/commenting on one page, the one piece manga has changed quite lot from back then when the anime did 2 to 1s, no longer are the backgrounds clean now every single millimeter on the panel is used up with stuff going on the background and foreground, they do quite often do 1.5ch to 1ep but it sometimes resorts to them having to cut out background chatter.
-one of things that makes the anime so good is how it knows to build up scenes in a dramatic effect and knows what tracks to play & when.

Yes a 2:36 second scene were a man flips the earth & sea on it side, would of taken 7 seconds to read the in manga but just wouldn't be as satisfying or as dramatic.

some dude throws a log at 3 other dudes and yes it's hyped as fuck.

Takes 1-2 seconds in the manga stretchered to a boss epic entrance lasting over a 1min, you just can't do that dramatic effect in manga.
I do think marine ford could of been paced much better by cutting fat at the start of the arc shorting it by like 3-4 episode max but shorting it down by half would of require them to start cutting panels and I want my panels if they did that they would be no point in watching the anime at all.
