The uses I see for it are constant sustainable supers to near instantly clear out any prominent threats. Ogre spawn on crota fight? Golden Gun and Radiance nades, double golden gun, double nova bomb, etc. Need titan bubbles up for support? Well now you have them infinitely, with infinite weapons of Light and blessing. Waiting for the bridge to spawn in the abyss? No problem. Swordbearers? They dead. Wizards? Can't touch you. Conflux? Nova bomb, gg, foh can clear those repeatedly. VoG gatekeepers? They're a joke. Don't have gjallahorn or icebreaker? Contribute to spawning titan bubbles, or contribute an offensive super instead. I used to say my favored raid team was two of each class. With a Gunslinger, Bladedancer, Sunsinger, Voidwalker, and two defender titans using both blessing and weapons. Now I want four titans and don't care who the other two are.
