There should be a Hunter exotic for Gunslingers that give the throwing knife some love. The throwing knife is a very unique and awesome melee ability, but unfortunately there are no perks that compensate it at all. There should be an arm armor exotic that gives you throwing knife benefits specifically, whether it be given perks like what Helm of Inmost Light does, providing perks on the skill tree. Also, New perks could be made. Throw some ideas down and if we get enough, maybe we will get get some love from Bungie and it can be considered.
