No, I'd rather have Radiance give bonus damage to my Grenades when active, and have Song of Flame lend that damage boost to other teammates' abilities, including their Supers. At the very least, I would rather have Radiant Skin provide a Weapons of Light damage boost to Kinetic primaries, and grant them Solar Damage. Maybe have Radiant Skin also extend to teammates. The most I'd want for Fireborn is a significant increase to movement speed and Recovery for you and your allies when active, whether you activate Radiance while alive or dead. Gotta think reasonably. It would be too much to give it something like bonus weapon damage while only holding a Super charge. Maybe while Radiance is active, but not just because you're sitting on your Super. Having Radiant Will act similar to Simmering Flaming, or the opposite of it, would be an idea though.
