Smoke simply does too much with just one node
Smoke (without any perks) should only take away the HUD and blind you
If you use venom, it gives damage when you are inside the smoke itself
The perk that allows to put smoke traps should also slow down the enemy when the bomb goes off/you throw it to an enemy, and with the perk "lockdown" extend the amount of time it can stay next to a wall.
THAT is more balanced. Right know, getting smoked --> 1% of survival
Edit: they could increase the radius to balance it out

This is why we can't have nice things... If you seriously think smoke is overpowered then I don't know what to tell you... Every other subclass including the Hunter has a grenade that one hit kills enemies. Have you not been seeing the gunslingers running around spamming tripmines with maxed discipline?!! Yet here you are complaining about the most neutral sub class for PvP other than defender titan. Half the times people just walk right out of my smoke with a sliver of health left...and even if your shields are down, a smoke won't kill you with a direct hit...so stop complaining!
