So, every strike I always start with just about half Ammo on my heavy (Rockets are always full for some reason at start) I then after going thru all my ammo... See zero drop. When I do it is sometimes towards the end of the strike at the boss... Or at the very beginning of the strike. I went 5 Strikes with only my starting ammo and seeing only 2 Heavy bricks drop... WTH is the point of the Perks if there is no increase in drop rate on kill....
