In my opinion, Fast Roping has it's Pros and it's Cons. But instead of everyone trying to Knock it down and say no, Dont put it it.... Why? It WOULD be nice to have the Options available to you. I've had tight spaces where I needed to land a 12 man Group.... But I couldnt! I'd have to slink around, maybe find a nice open plot in the city or Land outside of the city and make them have to walk into an Objective where as I COULD of just came up to a Target zone, Doors open "Ropes, Ropes, Ropes" They Fast Rope down and I'm out of there. Basically what I'm trying to say is, Instead of everyone Arguing at one another because they think it's Awesome, and the Other thinks it's stupid, Just come together on a Common ground and think this way.... Let BIS put in a Fast Rope Capability.... If you like it? Use it! If you dont? then Dont! It's as simple as that.
In Closing,
I think it's better to have the ability and not use it, Than to need it and Not have it.
S.O.E.
