I'd be down for some hive magic, but keep in mind that their magic is fueled by death and sacrifice. Not sure how the vanguard would feel about using such tactics but you could design subclasses that are based around killing an enemy (who is basically the sacrifice) and in return you get buffs/bonuses. [b]Warwick melee[/b]: strike a target with a hive magic melee attack, that corrupts and slowly drains the target a portion of their health that is then given to you. If the target dies, they leave a remnant that can be picked up. Picking up the remnant temporarily applies a corruption affect to your kinetic weapon (legendaries only). Targets that die from corrupted weapons grant melee energy. [b]Warlock grenade[/b]: a hive corruption grenade that can be used to slow down targets and suppress them. Alternatively you can consume the grenade to temporarily apply a corruption effect to your rifts. Targets that come too close to your corrupted rifts quickly loose health. Damaging targets while inside your corrupted rifts grants grenade energy. [b]Warlock Hive Super[/b]: basically you become a walking thorn hand cannon. A deathly aura surrounds you that can drain nearby enemies of health. You can also shoot large corrupted javelins from you hands that quickly poisons targets. Targets that come near javelins shot on the ground will loose health, direct hits will cause targets to explode spreading corruption damage to nearby enemies.
