I don't know if this has been discussed already, but I was thinking about transit gates and intrasellar communication. For example: if a SU gate is taken by FC or Ijad forces, and there was no gate traffic during the conflict, then further SU forces would be taken by surprise the next time they came through. That should work for sure at least once, possibly more times if we start taking about multiple other gates connecting. Especially because of the (presumably) slow nature of information being disseminated through a factions gate network.
This also would work well for invading other gates, because if the last contact a transit gate had was friendly, they would presume the next contact would be friendly as well. I think this is supported by the provided game material, where it mention that several of the ships can sneak through enemy gates because they have a civilian profile.
Of course as time goes on, and the conflict expanded, perhaps transit gates would always be on guard during an incoming transit. Possibly fully deploying all Ships and TTM frames at the time of connection.
What do you think?
EDIT: I meant interstellar, I was thinking of intergalactic (face palm)
