Here's what I honestly think... people are farming these weapons wrong. I'll admit... I looked up a tube vid, a few actually... and I did exactly what they did. The spawn rates for heroics was averaging 30-45mins... no way, I couldn't do it. So then what I started doing was doing at least 1 regular patrol before I refreshed the instance from the PE node and rotated through the zones... sometimes I would do 1 patrol per zone before I refreshed the instance... Admittedly, I can't state exactly... if doing 1per or 1total was the trigger but, after that, I was getting heroic patrols to spawn sub 10 mins. I got the rest of my weapons unlocked last night in like 2... 2.5 hrs (2.5 Conan podcasts, lol). I can't guarantee this will work, maybe it was just a coincidence... but I had being trying all week with the tuber methods off & on... and 0 patterns dropped, the heroic spawn rates were abysmal. Then I started mixing in some patrols before I refreshed the instance, now I'm done. Do with that, what you will 😇👍💠.
