SL Trackers were added before my time, so I can only realistically speculate. But I’ve always viewed SL Trackers as a way to help new players know where to go, seeing as new players will almost always start as an RFN with no map knowledge or idea of what to be doing.
In my eyes, at least, organization implies a level of active communication about what is going to be getting done. When I see a murderball, the extent of communication I see between marines is which direction the Queen is coming in or if there is a flank coming from immediately behind the murderball. It is because murderballs require little communication that they are formed so often, they require little to no effort to figure out and little to no effort to keep going. However, it’s for that exact reason that I dislike murderballs and find them unfun.
By having all the marines bunched up in one location and fairly-thoughtlessly shooting in one direction, you wind up removing most opportunities to actually create memorable moments in a round. You don’t have a chance for Delta to pull of a stunning surprise maneuver to decimate the Xenos (even if it doesn’t go that way 9/10 times). You don’t have a chance for Charlie to discover a Xenomorph flank ahead of time by scouting out ways to move around the frontline. You don’t have Alpha patrolling the backlines in Fireteams to gun down lurkers and runners. You’ll probably still have Bravo fortifying comms, but we better hope that they don’t lose it because we all know they won’t be able to take it back without help.
For me, at least, when I tell marines to “stick together” I am referring to their individual squads. If I want Alpha & Delta to bunch up, or Charlie & Alpha to bunch up, or Delta & Charlie to bunch up, I explicitly state it. If I want them to separate and pursue separate tasks, I explicitly state it. And sure, there are implicit roles that each squad marine plays when they’re all bunched up in a murderball, but I’d hardly call it the peak of organisation precisely because it’s implicit - it isn’t being actively communicated and planned around, it just happens.
Also I’d say it’s a stretch to call restoring comms, repairing the sensor tower, or flanking a “murderball on a smaller scale.” Unless you consider any group of marines moving together a murderball, that is.
