I have never met a more suicidal god-like captain in the history of Destiny. When you're at this point of the encounter, the encounter can get pretty cheap and result in stupid deaths. When he spawns in, if you throw a grenade at him, he jumps off the map. If you rush him with a shotgun, he runs behind cover when his life is low, and he either jumps off or is knocked off the map. If you pop a stromcaller, he runs and jumps off the map. Remove him shield with a suppression grenade he runs and jumps off the map. The result is him randomly showing up behind in the middle of the encounter and killing you with the scorch canon. I never knew how big of a problem it was until the hardmode came out, when he kept coming back to life after committing suicide. If he jumps off the map, he should stay dead; of a barrier has to be created to prevent him from falling off the map.
