People just dont want to waste time doing FR with people they dont know. They want fast runs, and if they dont know you, theyd rather not join you. I have a squad that I always join and we do FR for 25to 30mins per run.
Also, add PE in BH, Hide and seek fking gives you15 PE, heck even just joining ctf and hb ,still gives 3 PE when you lose and it's every 2hours
