As much as I love finding something rare in an average loot box they all seem to be the same in regards of number of items and how much is in the stack.
I suggest military style loot boxes, much bigger and more rare to find but has top tier loot! ALL ARMOR PIERCING ROUNDS, grenades, landmines, maybe a 4 or 5 star attachment. And advanced first aid kits.
I WANT THE MACK DADDY OF LOOT BOXES
