Hostility points

[Hugh Latham]

It is illogical that an attack on a port a great distance from ones own ports or those of an ally would have the same difficulty a those adjacent to said ports. I think hostility points should be a factor of distance from ones own ports or those of an ally. This would simulate the difficulty long supply lines would create and produce a more natural expansion of territory.

Since both alliances have territory spread out all over the map, that wouldn't make any difference whatsoever. Also, if anything, attacking long distance should be easier, not harder, to encourage the challenge and risk that people take to do it.

What challenge and risk? With free ports scattered throughout the map you can move a fleet unseen very close to the target region by the magic teleport after capture in combat.  Just drop a war supply bomb and log your fleet out in front of the harbor so you can't be screened.

As I said, if your ally has ports closer you would use those ports to measure the distance.
