By the same token, they should remove honor charts because it might allow someone to figure out a monarch's actual nobility title.Personally... I think the KD page delay is much better than real time pages.
Real Time pages is basically free intel, someone attacks, just refresh the page to see whose nw dropped. Worried about a possible soldier block? Just check to see if a prov's NW increased while you were preparing the attack. It's only free intel.
This 'free intel' should be part of the game.
If you are perceptive and lucky enough to spot it when it happens and capitalize on it, good for you.
However, I assure you that it will rarely play a role in the game (not the scenarios you described anyways).
Lets be honest with ourselves here, the lack of up-to-date info on the KD page screams "We would like to provide it to you, but can't pull it off atm" rather than "We did it deliberately to enhance your gaming experience".
In other words, they are caching KD page results in memory because the database can't handle the load... there, I said it.
