I guess I'd say it's OP if Sunsinger was any good without them. Sunsinger is straightforward. Excellent grenade, excellent melee ability, & that's it. There is no extra passives that help out like Pulsewave, Shadestep, Keen Scout, Shoulder Charge, Cauterize, QuickDraw, Invis... Nothing. Sunsingers literally have no extra abilities that make them cool. They have a fantastic grenade and melee and that's it. And to add to this, their super game is literally the exact same as their neutral game. Without those firebolts w. VF + ToF Radiance is trash too.
