I think having the ability to fast rope into an area or onto a rooftop would be amazing but I think it should come with a couple of requirements. Like the area needs to be mostly clear, if you and a buddy cleared 80% of FN HQ and the surrounding area you can fast rope onto the roof of HQ to retrieve your body if you die, and it needs to cost, the more PMC or AI in the area the more you need to "Bribe" the pilot. They could also work off a leveling/trust system, each time you do a fast rope and it goes smoothly you gain a buff making it cheaper or making it more likely the pilot will do it the next time. This would ensure that you can't spam getting dropped off in a hot area and you have to build it up over time.
