It amazes me how so many people in this community are blind to the actual perks of the sunsinger class. It's not all about self Rez, especially for Crota cp. First, no one should be dying anyway, it throws so much off. Second I run sunsinger everytime I'm at Crota and not because of self Rez! It's because of the apotheosis vail helmet and I reduce the cooldown of all my teammates supers when I activate radiance.
