To be specific, it's the only ranged area attack that can be fired off "without limit" and unlike GG's Firefly perk, these hammers can explode no matter what. There is no requirement to causing splash damage like GG has, and unlike the Sunbreaker, you only get one shot as a Voidwalking warlock and your super is done. My own "fit" is well pitched and not without reason or logic. Yes, it's good that it behaves like the other ranged supers, but it is still far more powerful than them, even in the hands of mediocre players.
