It could be real handy. Many tycoon games have it to make lives a bit easier. I know this isn’t a tycoon game but it is quite similar in regards to thralls and base building.
Since settlement system was slashed by the devs, why not a zoning system to keep certain thralls in that zone and disallow them from breaking ranks, or even create a pathing zone to have thralls move around, as if patrolling, like say a lengthy wall for example?
This would make the base seem more alive than an immobile object.
Also add some musician thralls that play instruments… my dancers are dancing silently and it looks awkward as hell.
