You make some good points guardian. The lamps suggestion is great. Also the bridge portion because of the spawn lanes makes sense. I'm still taking gjallarhorn over DB in the hallway section and at ir yut. Gjallarhorn shoots faster than DB which is important in the hallway section because time is of the essence. For the deathsinger encounter, the damage from Wolfpack is greater than the solar flare damage. Gjallarhorn reloads faster so you can dump the rockets into her faster. If you get to ir yut before she begins her countdown she is extremely shifty, so tracking becomes big as well. I think DB is viable in the raid, as long a skilled hand is using it. Gjallarhorn is just so ridiculous it overshadows anything else.
