You think it's easier to land 4 headshots on someone or to mow them down and get a precision shot for an auto rifle than to one shot them with a grenade? It doesn't have to be connected to the super. Hunters and warlocks don't get mobility buffs, increase reloading, or weapon buffs that stack on their supers. Let's look at ease of use though... Fleetfire- any grenade or melee kill. Or hammer of sol kill. (HOS runs out and you're buffed and agile.) Chain of Woe- depending on weapon you take on average 1.7 seconds of headshots. If you finish with a body shot, it doesn't work (I main scouts) Surge- get in close enough to a weak target, and KILL them with a melee. Alternatively, run Embrace the void and deal damage with a grenade.
