Agreed.
They even picked Midway as an example to show us; and you can see how terrible her huge deck looks sparsely populated by a handful of planes. They're all spaced out so weirdly too. What historical reference have they been looking at, if any?
That said, who even looks at their carrier deck and counts visible planes to determine how many of them they've got available? You press ALT and can see a number. The enemy can't use that at-a-glance information either, since you can only see your planes on deck and no one else's.
Seems to me like a change for the sake of a change.
I got a Kaga recently and she looks amazing with all those planes stacked up on her deck. It looks good.
I don't want that to go away, if they must make it an option to "depopulate carrier decks".
