The Division 2, Guardian Builds. Watched some YouTube videos with a few of these, needed one cause they were pissing me off. Started with the recommended setup but didn’t like how it performed if you got jumped by mobs when fighting boss, it happens a few times. Changed 4 gear pieces one with some blue all over it 5 red 1 blue core and it did just about as good as the 6 red core on the big pop. Had way more survivability and quite a bit more shotgun damage but need to be pretty close. I was able to kill all the Guardians around 20 minutes, I might post the build after a few more days of tweaking it more. Specter is still the toughest, kill him easy but he is the most damaging and aggressive. My play style is just crappy using a shotgun and needs more practice.
Weird thing, maybe I don’t know something about this containment mode. Today when entering Central Park I had to fully redo all the bosses again with the aggro meter by killing mobs first. I don’t know if this is how it supposed to be but seemed odd. After than it worked like normal and was able to farm all them a few times over. Another weird thing I was playing with in the Open World area next to Central Park, Guardians kept spawning near the borders at times fully in the city. Was able to kill two, 3 of them bugged out and disappeared. Bunch of people joined and complained like wtf is this guy doing running around non stop. Made a little route that was pretty good to find them in the city, mostly up in the northern areas.
