Best example is the Rocketyard. People actually run around killing mobs they could kill on patrol and then run back to kill them again as they respawned. On their way they pick up spin metal and look out for chests. Sorry guys but if you want to farm glimmer there are more efficient ways than killing 25 red health bar mobs for 150 glimmer in roughly 5 minutes and hoping for an engram to drop. Do this on patrol, not when the goal is to kill a boss and get a guaranteed reward which even if dismantled also gives glimmer!
