Army of One: "Quick unassisted kills with this weapon reduce grenade and melee cooldown." This perk does not work on vex enemies for some reason. I have recently been using a Sunsinger warlock build focused on my Sunbreakers gauntlets and my Reflection Sum (Adept) - which has Army of One. After a while of using this build, I've noticed that Army of One does NOT trigger upon killing a Vex enemy. Please fix this!
