Not sure about servers I haven't been to (not a bandwagoner, only transferred once, recently), based on own experience there's a lack of scouts and havoc groups. I would propose for a universal way to scouting and offer a suggestion based on what I do which many have found useful in-game.
What I do when I roam with my DE is I tag up with a white tag (neutral colour) looking for enemy blobs. Whenever I spot a group I change the colour of my tag depending on the colour of the opposing faction (either red, green or blue) and follow them around the map to report back about enemy position, numbers, possibly roster if conditions allow it.
I see no flaw in this system since the implementation of multiple tag colours and more tag colours could be added in the near future. It would only seem reasonable for a universal system of this kind become a standard.
What say you?
