EDIT: Discussion moved to public: Auto-squads for area patrol Well, as we all know, area patrol is a troublesome feature. While it surely helpful, it also gets very troublesome for the server as soon as more than just a handful of units is patrolling due to the cost for pathinfinding. And then there is also the issue that most units are pretty much useless when straying around individually. (Unless for scouts. But then again: Only a limited number of scouts is required for full coverage.) So why not solve both problems at the same time? Whenever a large crowd of units is set to patrol an area, automatically group the crowd into squads of 3-20 units, depending on the size of the crowd. Units inside each squad move in formation with common goal. Squad size isn't fixed, so if new units are added to the patrol group, they get attached to the nearest squad. If squad size exceeds a reasonable limit then the squad splits in half at next waypoint. If the number of squads exceeds a reasonable limit, a simple "easiest match" is performed to merge two squads which are below the size threshold. Both thresholds scale dynamically with the total number of units patrolling per planet/command/whatever. As a bonus: For inhomogeneous unit groups, ensure that each squad has an evenly distributed unit composition, so you can just set factories to auto-produce your favorite unit-mix and have the area patrol feature group units accordingly.
