Well not entirely true. It promises who will be the host. But the exploit itself is sketchy since it involves a latency error. Meaning just because the host leaves during him kneeling or while he goes down it's not always going to work. Because of that alone I don't think Bungie can fix it. The best they might be able to do is ban people for doing the glitch or set it up so he doesn't drop loot if killed that way.
