The Division 2: Guardian Global Event- A Solo Player's wet dream or Nightmare

The recent guardian Global Event gave a lot of players the best experience recently in the game. You could blitz through any mission in quick time OR you could get wiped over and over again by just one red NPC. You would need to kill a guardian (indicated in green) as quick as possible to be able to kill the other NPCs. If you however, run into NPC with the red mark, without any guardian in sight to kill, well, let's say it's not the most fun experience.
