Below is my list of suggestions: 1) What if they just removed Firebolt Grenades and replaced it with a Solar version of Spike Grenade? Firebolts have and always will be trash in PVE so that isn't a concern. Balance wouldn't be an issue, considering that Sunsingers would only have one grenade which can apply the Touch of Flame DOT still, or two grenades which don't apply the DOT. 2) Song of Flame should be a passive buff while radiance is active, always. Also, give it a visual. Perhaps a circle of fire which follows the Sunsinger? 3) As a result of Song of Flame being removed and made passive. Offer a new perk which decreases melee cool down while radiance is active. 4) Solar Wind should be an Frontal Cone AOE knock back with a slight range boost. 5) Brimstone should also give the Sunsinger a moderate temporary boost to armor on kills with the explosion. 6) Radiant Skin should be given a slight buff to shield 7) Return Flame Shield back to former glory. Warlocks excel at melee. Deal with it. 8) Sunburst should be changed so that there's a % chance to generate an orb from any solar ability kill.
