Still doesn't solve the problem, lower the % too much and you'll have other items that would become the new "junk" taking up the slots and then we're back where we started.

Back when DayZ Mod was popular custom loot tables were a thing because of how much junk you'd find, and it was a pain to just go through the code figuring everything out even if you know what you're doing due to how loot spawns were handled, if you just look at CfgBuildingLoot.hpp you can see the % of the default item spawns pre edits.

Even with leveling out spawn % it's still going to pull from the same list. Vanity items are the only way to keep the loot evenly distributed currently until they have added more weapons, gear, etc. at which point there will probably be a new "please remove x item from loot table."

Hopefully when private servers are a thing we will have the option to edit loot tables to our liking though!
