He gave a .367 second time-to-kill on that. Assuming that he was killed by a single attacker, there are still at least two shots that hit him. Just because you can't react to a quick kill from the side or behind doesn't mean it's unbalanced. A shotgun kills even quicker from the side or behind with a single shot. Sure, a range nerf won't guarantee you'll win every encounter with the Last Word, but that shouldn't be the point of a balance. Before Bungie starts nerfing shit, they need to let us play on our large maps.
