The way we play quick revive isn't necessary. Revives are always simple as you are always split and can group all the zombies in your own area before sprinting to do the revive.
It is not just about the quick revive. It also makes the monkeys have to work 10 times as hard to even reach jug. QR isn't vital, but if you can easily have all 5 perks, you should get them.
Getting into the jug room after being downed is a bit tougher though the bottom if you dont use the lander, but it is a lot easier to get out of the jug room using the bottom than having to force your way back up the stairs into a small room for the prime spawning location of the zombies to whoever is on the platform.
