Idea for sentry plane.

Why not make the sentry plane able to see a players movements in real time. Player A could see Player B's movements before the next turn and plan accordingly.

Good idea or no?

No, because it would majorly fuck with the server. Not only would it require a complete restructuring of at least the netcode, but it would also heavily overload both the clients and the server as the server would be constantly sending out requests.

It's a bad idea from the game perspective too because it literally destroys the element of surprise in every single way. Impossible to implement, and bad.
