Even rich slavers can fall (or be pushed) into debt on occasion. And when they do, better to use their skills rather than simply treat them as useless cannon fodder.I wonder if you can provide control collar mods to Subjugators and Overseers... That would imply taking Syndicate society in a very different direction.
After all, what's the only thing better than an overseer to handle the nitty gritty details of making sure your minions perform adequately? An overseer who does so while being literally incapable of opposing your orders.
