at this point i Think Most of the Titan Exotics needs some help and Armamentarium is def one of them. A neat buff i can think off could be to add a "Demolitionist like perk onto it, so it reloads all equiped weapons when you throw a greade and kills restores grenade energy". i think just adding 1 extra grenade is kinda weak when i see stuff like the "Dragon shadow" on the hunters that basically gives 50+ mobility / reloads all equipped weapons, better handling, reload and much more.
