It is so good it will be the next nerf.

Neutral game. The super sucks dong for the most part (few circumstances where a nova bomb or golden gun would be better), however the envenomed smoke grenade plus the vortex/voidwall grenade is a deadly combo. Smoke damages and keeps them slowed, and trapped inside the grenade's damage radius. This coupled with max strength and disc makes NS VERY dangerous in the right hands. Also, shadestep (defensive get-out-of-jail-free card) and keenscout (wall hacks).
