Sensible.Yes. Also, the League has been doing some 'renovating' since Grayven jumped ship.
When your tech support guy jumps ship, probably a good idea to review everything just in case.
No.... Meaning they ripped out all the useful bits and pieces of technology that helped them protect Earth over a petty grudge.
Fucking Justice League. Morals I can understand and respect but the way they go about it sometimes is almost as idiotic as the Light.
Means that they took Grayvy's advice and changed their operating protocols after Grayvy left.
We have no suggestion that they would have reduced the security upgrades on the Watchtower; they are not morons.
