Prove that they are op: they deal 50% more dmg than axion and arc bolt and stop recovery for over 10 seconds. It's the grenade with the most range were it deals full dmg in the game except for the bouncy bladedancer grenade. Aaaand it is weak withiut the perks, which could be a reason sunsinger has only one build. Rework sunsinger and remove melee shield on hit and make burning names a basic. Skill while in radiance :)
