No , that only triggers on cast , this guy just copies . <| sep |> What I think you ' re missing is that Sunsinger is designed to be a support class . From Viking Funeral to the lowered team cooldowns to the orbgenerating melee to the strong defensive buffs , Sunsingers are not meant to be an offensive class in the spirit of Voidwalkers and Stormcallers . However , Sunsingers have the added benefit that they can do more boss DPS than any other class aside from a Celestial Nighthawk Gunslinger . Sunsinger spamming Fusion grenades is an incredible DPS strategy . Like you said , it does as much damage as a Black Spindle , but ONLY if the Black Spindle crits every shot . But who is really wasting an exotic on Black Spindle in WOTM when Raze LighterDark Drinker are far more useful for the add phases ? A competent Sunsinger can also combo their fusion grenades with a cannon during Aksis . This means you are individually doing a Black Spindles DPS , plus a 15 % team buff for roughly 12 seconds of DPS , plus firing off your remaining 7 cannon rounds . Properly primed and WOL ' d cannon rounds do in the neighborhood of 130 k damage . So just your cannon alone is topping off north of 900 , 000 damage . A properly kitted Sunsinger can generate insane orbs . For one , there ' s the 21 orb melee during Crota ' s End . Also , if your goal is orb generation , then you want to be rolling Solar grenades and Sunbreakers . Max discipline , plus Sunbreakers , can generate a ton of orbs during a Sunsingers Radiance . In addition to putting out a wall of fire they can essentially last in excess of 20 seconds 12 ish second super , plus the 8 . 6 second burn of each Solar grenade , can give you a constant AOE burn of over 20 seconds . So the trick with Sunsingers is optimizing your loadout for your role . If your job is add mitigation , then Solar Grenades , Brimstone and Sunburst are going to be more beneficial . Do I think Sunsingers can be better ? Sure , why not . I actually like the idea of Flame Shield being an AOE radius team buff . But I find too many Sunsingers I play with in PUGs don ' t optimize their loadouts for the activity . Similarly , I was playing in a PUG with a Voidwalker who was rolling with Vortex Nova Bombs and he couldn ' t understand why he wasn ' t oneshotting captains in WOTM he was also using Blink and couldn ' t figure out the few times he inadvertently leapt off the edge . So you just need to optimize your perks for your game .
