In BtS missionaries and corp execs can and will spread their thing to nations you have an open border with. In RoM, RoM/AND and early C2C they could do this to nations you had RoP with and they did. However HN and Criminal units were introduced and now the missionaries and corp execs get killed as soon as they enter any foreign territory.
Not very realistic! The missionaries in particular are good decent people being murdered out of hand. Same sort of goes for corporate execs and eventually diplomats.
There should be a huge hue and cry by the people of that religion from all nations as well as demands for action from the originating nation. Each time it happens there should be a diplomatic hit between the murdering nation and all nations that have that state religion as well as the origination nation. If it is the missionary is of the state religion of the murdering nation then all their cities should also take a large unhappiness hit for 5 turns each time a murder occurs. Eventually sanctions should be drawn up against the nation and all trade cut off until the criminals are brought to justice.
Of course if you are running the "Closed Borders" then you should not be able to have a RoP or OB in the first place.
Just my opinion but here are my thoughts:
1) demands for action by the originating nation would need to be able to identify the originating nation. For a diplomatic hit to apply, the nation would have to be identified. Currently criminals and strike teams, pirates and ruffians, have no mechanism like spies to potentially give away who they are working for. I've considered trying to study the spy code to give something of a mimic to that if they are dispatched or arrested. When I consider that, it gets really complicated and no real simple mechanism concept emerges.
2) missionaries are killed in foreign lands in real world Earth all the time! And it's very rare to know who did it. Corporate officers would fear to tread in many lands on Earth today and what do they do about it? They pay for militarized guards when they go into those regions.
3) it's better for gameplay that any goal has numerous methods by which they can be thwarted.
That defensive promotion also gives specific benefits against criminals and strike teams. The AI is even using it properly to an extent without the new dedicated escort AI I intend to design for them. If you were to group such a promoted unit along with a missionary and set that missionary to automate spread, I believe they'll travel as a group to achieve that goal. (Not confirmed yet.)
The point is I'm trying to help make these stealth units functional, yet not overwhelming, counterable but not useless. Striking a balance between you and SO on this is getting to be a nightmare but you've gotta admit I've gone to great lengths to try, regardless of how much flak I get for it.
Oh... one more note:
I was sure settlers could not enter territory with a RoP
The only rule setup before I tweaked it so that Law Enforcement units could get a tag that allows them to be capable of attack and still capable of using an RoP was that units that cannot attack were those that could use a Rite of Passage. This includes, and always has, settlers. You've never seen them USE it because they won't ungroup from their escorts. If you want to give them a specific tag to say they CAN'T use a Rite of Passage despite being incapable of attack, that's another thing entirely to setup.
But then... isn't Joe's scenario kinda interesting?
Of course if you are running the "Closed Borders" then you should not be able to have a RoP or OB in the first place.
Agreed. Haven't taken the time to analyze diplomacy coding enough to have an idea on how to make a tag for civics that would tie into that. I kinda fear diplomacy coding in general as a can of worms in and of itself.
One more footnote here... one of the major inspirations for that promotionline is the historical Knights Templar, who for many years prior to excavating the temple mound in Israel were employed as guardian escorts for merchants and pilgrims travelling to the holy lands, giving them the opportunity to make the way safer to a place where without them, no travellers could feel safe to go. In the equivalency in C2C, these would be Crusader units with that defensive promotionline. They weren't alone as far as medieval militarized guards go either.
A promotion set for merchants is not quite sufficient imo. It helps and is reflective of a small group of guards or some self defense training but those units will never be able to be brought to be strong enough to defend themselves without making promos that are simply far too strong for a promotion to be.
