Don't have a name as I just though of it. For the Warlock, the super could be similar to the Titans bubble, however upon activation, the Warlock jumps in the air triggering a bubble of lightening in and around it(with a limited distance obviously). The bubble does not provide protect, merely ultimate destruction in a short amount of time. However, maybe some perks could decrease the damage dealt by allowing a temporary arc shield for allies around it and yourself? Useful for when you are getting swarmed. Or the warlock could have a more versatile super. Upon activation, all allies and yourself, gain boosts to health, damage, movement speed, etc.. The perks could allow the Warlock to choose to help himself or aid his team also.
