#27 Bridgehead vs highway

[Markus Armbruster]

Smart players never make coastal highways, always
bridgeheads. Obvious reason: can build bridges, just
in case. Non so obvious reason: bridge heads have a
superior defensive factor (1.5 rather than 1.0). This
doesn't make sense.

I propose to give them identical defensive factors.

I further propose to abolish bridgeheads and anchor
bridges at highways. If that breaks clients, keep the
bridgeheads, but remove all differences between
bridgeheads and highways.

[Markus Armbruster]

Defensive factors are identical since 4.3.6.
