A tactic arose recently in regards to port contention. Players (and their alts) would take unrest missions and hold onto them. Once they all had unrest missions, they would turn them all in at the same time, and push a port all the way from peaceful to having a port battle scheduled.
The reason we have these missions in the first place is to allow rich players to spend their money in ways that directly impact the game world. As secondary goals, missions create markets for items that dont necessarily fit into ship production, and create a demand for those items. Also, the missions drain money out of the economy in a purely voluntary way. These things are all basically Good.
The problem is that we clearly never intended for players to be able to take a port from 0 to 5k or even 10k unrest instantly. While were biased towards attackers (we like PvP!) this goes well beyond bias and into the realm of insanity. Defenders should be able to draw a line in the sand, declare a port off-limits, and enforce that with doubloons. Thats not currently possible. Worst of all, this tactic can be used on new player ports just as easily as on ports in the Antilles. New player ports are intended to be harder to attack, and this process circumvents all the tuning we did to make that the case.
