I had an idea for an exotic that enhances quiver. The super charge lasts indefinitely until all three shots are fired, but your super won't recharge while there are any remaining shots. So you can have an on demand but weak shadow shot. (Personally I don't use quiver I just thought it could be a cool idea) Especially considering people use it for kills rather than tethers anyway, and even tethering someone/something doesn't stop them from shooting you to anyway... Functionally it might as well be the equivalent of a shorter cooldown, one shot per use quiver if they do hold off on using it since their super won't recharge anyway.
