This is just my opinion but i find it works great for a lot of missions, strikes and raids.
Grenade- Vortex. I like this grenade for killing slow moving eniems and groups with its fast damage ticks it really works well.
Glide- what ever you like.
Nova Bomb- Vortex for damaging enemies over time. Shatter works to for dealing it big groups of enemies.
Energy Drain- i like to use soul rip to reduce nova bomb cooldown.
Perk #1- battle recovery and speed. Mobility and keeps you out of the fight for less time giving more kills and damage.
Perk #2- i like to use annihilate for bigger nova bombs and coupled with the nova bombs vortex massive aoe damage and bigger grenades.
Perk #3- speed mobilityi find is a great compliment to the voidwalkers allowing great bursts of speed to help get out of trouble. If you prefer some tougness use all attributes.
Perk #4 Vortex Master or Bloom either works vortex master increases duration of vortex grenade and nova bombs vortex and bloom to cause enemies to explode from any abillity kills
Armor i would suggest future war cults for the intellect and discipline to help generate grenades and nova bombs and if you have dark below dlc the obsidian mind helmet is a great compliment for getting faster nova bomb cooldown on nova bomb kills.
Final remarks this build may not fit everyones playstyle but it works for me also i recommend the bad juju again to help with nova bombs.
