NPC RAIDERS

[Never]

As I understand it, if the port raid is won by the NPC RAIDERS, the port becomes neutral?
I think it would be a lot better if the port became damaged instead, the amount of the damage depending on the number of AI ships left by the time the battle is won by AI. (more raiding crew  cccan take more loot and do more damage in the process). Repairing the port could require something similar to port investments. 

The port becoming neutral seems way too much of a penalty for the loss, since it is not a normal PB, the result shouldn't be the loss of the port.
