From an information theory perspective, it should be possible to define strategically important locations in terms of Empowerment [1]. As a map designer there are likely some rough rules you want to abide by, such as roughly equal highly empowered locations throughout the map to reduce location bias.

I remember an old game where they defined map rules in FPS CTF maps that there should be more than one path to each flag (usually three) and flag areas should be partially visible from one base to another. There were lots of rules like these, some more flexible than others.
