I have a suggestion for a grenade that could replace the Hunters Voidbolt grenade since it already exists in the form of the Voidwalkers Axiom Bolt grenade. How about a grenade that could instantaneously travel towards the direction you throw it (with a maximum distance on how far it could go of course) and once it does damage to a target they are slowed down for around 2-4 seconds (the amount of time changes depending on the targets agility stat in PvP). Maybe call it a snare grenade or something along those lines.
