You could simply leave it at “5x the health” because that alone is enough
Plus, i don’t think you can find a Minigun in a Military base… you were basically forced to go to a deadzone to get the high teir loot
But I do agree that most if what you find can easily be found in other areas so there should be special weapons that can only be found in Deadzones such as a Legendary Quad-Stack mag that can hold 200 bullets. Or “House Cruiser” a mega backpack that has 1.5x the space of an Alicepack
The least teir loot you should find would be grenades and ghillie suits
