The Nightstalker subclass was originally going to get the perk named "Well provisioned" , this perk would grant the class a second grenade and increased duration. This perk has been replaced by one called "Lock down": Grenade and smoke effects last twice as long, allowing strong territory control. -Yes this perk is good in the sense that it will grant crowd control -Yes it's good they included smoke However, the previous perk was more beneficial and finally gave the hunter the ability to have two grenades just like every other class can have. It was fair. Now the hunters are getting the short end of the stick again when it comes to double grenades. Bungie please return that perk, hunters deserve double grenades as well.
