Thank you for suggestion.
Not sure about NPC villagers, but NPC warriors is planned for your group, and planned such NPC as lumberman, hunter, blacksmith (or it will be just buildings). I think about NPC traders. NPC are planned in the end of alpha stage.
Instant construction will be removed, sure. There is a one detail with building by NPC and transfer resources between storehouse and construction site: i intend add outpost (mobile clan respawn for war campaign) and if i want to build far away from storehouse and i have all resources with my group - why i need NPC villagers or need to build local storehouse?
