Farming rooftop a bit slower

[JuniorVV23]

My idea is: have 4 players over 75 that can acquire the mission, all of them calls martin, the chance that at least one of them gets the mission is high, then who get it call the others; and then after its over go to free roam and all the 4 call again, and keep it going. Ofc it won't be 25k/4k per 30 seconds, but it will be per 2-3 minutes which is still pretty doable farming.

 

Anyone up to do it on xbox live? I am lvl 100 and need 3 more 75+ players that can acquire the mission through phone.
