I havent played since the new update on 6/14 but TBH, I really like my sunsinger and for more than just the self-res. I love pairing gift from the sun, and fusion grenade with Heart of Praxic Fire and a full Discipline build. I use Radiant will and Radiant skin. I can chuck 15-17 grenades and if I stick a strike boss with every grenade, it easily takes them down below half health. Outside of boss fights, its really fun playing as a mobile artillery piece using solar grenades.
