Sorry in advance if I'm not supposed to make a new thread for this, or this has already been suggested.
I was thinking, wouldn't it be better if you could only select one or two gates within the same pclaim/vclaim/vicinity to apply the "visitor" buff when someone crosses them?
I think this would still allow the intention of letting outside people enter villages without putting the entirety of it at risk, and yet also help with balancing against plot villages which have otherwise been "buffed" by this new system.
So, as an example you could have a couple of gates leading into areas of the village you wouldn't mind visitors wandering around in (perhaps a trading hub or something similar), while the rest of the village is still vulnerable to raiders without them getting screwed over each time they cross a gate.
