I think they should implement parachutes because it would add a WHOLE new aspect to PVP and exploration, Also, it would stop fall damage, for example, imagine you're running from people in hungergames and you are on a tower. Normally, you would basically die either from the players or by you yoloing it. But, with this you could make an amazing escape (Especially if they don't have parachutes.)
I also think they should add an in-game recording system with a hotkey like F8 or something because exiting your screen and waiting for the system to open is wayyy to annoying :/
