Something I noticed about Call of Duty Black Ops was the belly flop functionality, where you press the crouch button while sprinting you make a leaping dive. And in Crysis we can sprint and slide while shooting, climb buildings, and super stomp. But the problem is people don't tend to use these maneuvers when fighting due to the quick kill times within those games, it's easier and faster to just gun down your opponent then slide and shoot him. But in the manner in which Bungie makes health systems, you DON'T DIE IN 3 SECONDS. So it may actually be plausible And before you say we don't have enough buttons on the controller, Crysis and CoD already did it. I'm sure Bungie could do it also. It would make CQC a more viable option rather than getting gunned down from a DMR/BR type rifle every time from a distance. If you can dive roll, slide, and parqour towards this DMR/BR user, he'd have a harder time killing you. And you could land your Shotgun blast to the face.
