The warlocks Light beyond nemesis is basically the same as the alpha lupi for hunter and titans. Each has a faster revive and orbs. In fact they do the exact same jobs and its easier for us to get to 30 because we don't have to get a raid helm which eludes me still. Warlocks Heart of Praxic Fire makes the warlock sungsinger a grenade spamming machine because of faster cool downs while in radiance which to me is a far better option then 2 grenades from the Armamentarium to me. It is also great for creating orbs and clearing rooms of mobs far faster then any other class because it allows us to throw more grenades. So what titan will get a second grenade but in fact we will have like 11 grenades during our super and oh yeah carry 2 already without that chest piece as a sun singer. The two grenades work just like a warlock so its not like they recharge faster or both at the same time or something broken like that. Yeah its a good chest piece but so is the Praxic fire. Here you can see they have almost identical abilities. Id rather use fusion rifles in most of the content so its perfect to me. Heart of Praixic fire: has a faster cool down during radiance. heavy weapon ammo, and fusion rifle ammo Armamentarium: get's 2 grenades, heavy ammo, and special ammo The Void fang compares with the lucky raspberry if not better. Each one augments a grenade for a specif class. Voidwalker bolt already tracks players like a blood hound and now you get a 4th bolt which is amazing in pvp and pve and they hit hard.
