[Q]

1.) I think master computer can very well be corrupted by intelligence operations e.g. with a computer virus program. So I would not change that. I agree that the crew insurrection is at the moment to powerful, but if you increase it to level 4 intelligence operation there will be absolutely no defence against it at the moment because you only have counter intelligence level 3! I would prefer specific counter measures like a special loyalty component for ships and facility for planets. These components or facilities would greatly diminish the chance of a successful enemy take over of the ship or the planet by intelligence operations. The component or facility would however be expensive, so you would reasonably install it only on the most important ships and planets. Unfortunately I have not figured out, how to create this. I am not even sure that it can be done at the moment.
