Grapple hook functionality idea for additional use

So, I don’t normally do this with halo… I tend to hang around the Warframe forums more… But here I go.

It’s 1am and I’m not in the mood to literally draw a picture to show my idea, but basically I would be significantly more excited for the grapplejuice if we could also use it as a repel line, similar to how they used to use in the books.

Currently it seems like the grapplebapple is used by pressing the button then pulling you towards enemies and environments, or pulling a fusion core towards you.

What if we add the opposite effect for holding the button, so enemies are pulled towards you, and when you hit environment the line goes slack, so you could for example shoot a ledge, jump off and repel down, without killing yourself with fall damage or waiting for an elevator. (And I’d probably leave fusion core behaviour unchanged for press/hold)

Just my idea, hope the post isn’t out of place, and I don’t really expect any replies, we all kinda seem to be thinking about other stuff at the moment.
