With all the trading done betewn Town ,im surprise we dont see Caravan traveling the open world.
My idea is 2 Caravan at the Time would travel from adjacent Town , while traveling it could be raid by pvp player or could be defended. Depending from the starting Town the color identity would change , so a purple Town to a yellow town would have a purple Caravan.
nothing could stop the Caravan from moving but except enemy présence within 10m wich would make the Caravan slow down. This way range player could ambush the Caravan but unless they get close to it she would just leave the area.
For respawn : death within 150m would have a respawn of 30-45sec in a camp or instant if a Town or shrine is selected, if a player the same color as the Caravan Die with the same cooldown could respawn from the Caravan.
The reward from this could be RAW/Refine ressources for raiding and straight Up gold if defended.
Alot of pvp player asked for zone that force to be flagged but doing this would provide a activty that can reward more ressources but at a risk without preventing pve from farming.
This could also be a way to push influence too
