Well at least this piece seemed to me genuine and well thought thru. The only problem is that it took a month or two too long to appear. How much better had things been at the moment if something like this had some sooner?
For the CV spotting issue, could just removing the "planes spotted" indicator would go a long way to give DD's a bit more manouvering space? As a CV captain that indicator combined with the speed of the planes makes it really easy to find and pin down a DD that is trying to flank or just hide.
As for the initial start of battle spotting, maybe delay the planes leaving the carrier for X amount of time. That would give CV captains time to actually manouver their ship instead of like many just staying in the spawn point for the whole battle.
