So for those who haven't encountered this epic fight... every now and again a enormous amount of two different kinds of enemies spawn in a patrol area. So many that you can't finish them all before the event is over. I'm looking to compile some information on why this random event happens. Some people say spending 30 minutes in an area that two different factions of enemies fight each other will trigger this. I have tried a couple things such as clearing all enemies in a single area at one time with a strike group. Perhaps we should have finished all the patrols in the area first? Either way this needs to be common knowledge, please post any info you have on these phenomena.
