I would expect the cloud of Void Smoke to cause damage and slow enemies if this is the case. We could call it NightStalker and I would expect it to have damage with the support. A sunsinger has a few things that happen with their super, I expect that with our Void Hunters as well. I also expect a void Hunter to be stealthy and have some skilsl that give stealth like BladeDancer does.

Warlock should get a cone of lightning (due to his missing element being arc) but it has to be somewhat melee range. Titan needs a ranged solar so its hard to say for them....

I said that exact thing in another post!! Kind of I also think the super could be a "void clone" that distracts/damages enemies and other cool sorts of stuff. Or you can perk it to do... Other things...? I'm kind of lost on that but still sounds fun! A caltrops grenade that slows enemy movement speed and damage each step. A smoke grenade that makes you go invisible (team sounds cooler though). And a black hole grenade where you hold down the fire button to collect in coming fire, them throw it so it can burst the collected energy, or blow in your face if you get too power hungry. (I don't care what class gets that it just sounds awesome.) I also think it should have combinations from the original 2 classes, like throwing knife OR the ability to do the close range back stab.
