Sunsinger - besides decreased cd on abilities, give immolation so that any enemies surrounding the warlock take on damage. Maybe as an exotic? Nova bomb's shatter - instead of three orbs, give more orbs that aggressively track all enemies on screen. Like wolf pack rounds, but no aoe. Arc Class for warlock ARC super ability - warlock turns into a blue version of sunsinger and in third person view, you can still shoot your weapon (no actual damage increase), but similar to death from above perk for Titan's striker class, you can immediately aim toward an enemy, turn into lightning and immediately damage/kill your enemy, moving then to their spot in the process - like a lightning bolt. The farther you are, the more super you use, allowing in turn an escape component for PvE match ups. Think of Storm Spirit from Dota. Melee - Voidwalker surge would work here IMO as base, different modifiers will be considered here. Grenades: 1. Typical arc grenade that is for area of denial. 2. Another grenade that does immediate damage 3. A grenade that can be planted and discharged at will.
