It makes no sense to ban Assaultrons and Sentry bots from working as patrols and guards with conqueror. Even the dumbest raiders wouldn't use bots equipped with gatling laser and nuclear launcher as scrap collector or farmer. Even more so for Gunner and BoS. Ideally conqueror would check robot armor and damage to automatically decide if they are better suited for combat or worker. So we don't end up with protectron farmers assigned to patrol instead of sentries. Alternativly make bots freely assignable by players and even with automatic assignment on have them locked in the role and task the player gave them.
