Half of the time people escape the wombo combo anyway... I can't even recall being killed by it except for rare occasions when I'm in a position I shouldn't be in the first place. I main nightstalker and I'd say out of the many times I've used it...only a small percent of people actually die from the combo and not from me having to expose myself and burn their health a bit more to get the kill. It's no worse than a tripmine, since those can kill you much faster and don't take a full melee and grenade slot to use. Half of the grenades in the game now can kill in 1 shot...even at full armor. Yet the nightstalkers smoke + grenade combo only kills if you're bad enough to run right into it... If they nerf nightstalker anymore...it will be useless in PvP. It already has the weakest super alongside the titan bubble. This is why you see about 10 gunslingers or bladedancers to every 1 nightstalker in crucible. Nightstalker definitely isn't the best subclass for PvP and it's useful mainly for PvE activities.
