Secured Perimeter on PvE is terrible

Over 3 days I have 1 kill for the task I've tried luring them in, throwing nades, killing 1 PMC and running in, shooting them in the arm, walking slow to office, and killing tagilla they really need to add a spawn in the office love the game but this is making me lose it. I also can't imagine the lightkeeper task to kill PMCS around sniper rock no idea if that's been done yet or even tested.

Update: it’s done I got two after killing tagilla and two because they literally spawned right on the doors and were trying to lead the office GG less than 10 factory raids today
