This may need to be done carefully with the AI. But what if you could send out npc crew as basically glorified limpets to collect ground targets for you at ground sights. It would be a godsent for anyone collecting stuff during exploration. This could allow at least 1 srv plus you two speed up collection of resources at any landable resource location. Maybe even more than one crew/srv out at a time with you. this could lead to ground combat scenarios where you take a large bay with you to assault a location carefully. Maybe eventually commands like pets in most mmo's to coordinate assaults. Maybe a little better than most mmorpgs though. It's been done before btw in other games. They could find good templates. But this could lead to more missions types and activities in the future.
