So after spending countless hours making 3 characters, I've noticed that stacking heavy ammo works on armor, stacking grenade throw works AMAZING on armor, though stacking increased melee attack speed is not even noticeable. Like we're all stacked already, but shaving off .1 of a second or whatever really doesn't compare to throwing a grenade 500 feet in a straight line.
