I very much like your idea of the escort missions and would love to see them in game in one way or another.
I also agree with the AI spawning which seems kinda strange atm. Going to at least the edges of your terretory to kill ai seems like a mecanic that would make even the RvR system more interesting becuase people would start killing AI in border ports increasing activity there which in theory with the current hostility system would mean people are kinda ready to defend their ports whensomeone starts hostility or even make it possible for someone to at least partially flip the port by trying to kill players there.
The thing I feel like has to be implemented if it ever came to no ai close to capital ports is a way to run 100% safe mission with a low reward out of capital/safezone ports. That allows casual players who just have time for half an hour toshoot some ai than log off again without getting into PvP which might take longer and get them killed. The higher rewards in OW fleets will eventually get them to go and attack OW ai making themselfs targets but it keeps the game playable for many with very little time to play and let's be honest scaring away nnew players isn't exactly good for a game with a very low playerbase.
