Going to keep it short, the suspending dive on hunters is busted. Everyone knows it. It is a free kill in trials and there is little difference between being suspended and frozen in stasis. Being able to hip fire is not real counterplay when you are put into an awkward third person with your camera bobbing up and down. Not to mention you're put up in the air where you are easy to hit. It's just pure cheese like pre nerf shatter dive and stasis warlock melee.

Except you can easily bait it, and the Hunter is a sitting duck if they miss it. High risk = High reward. Just like a freezing melee, instant-kill shoulder charge, or a throwing knife.
