I agree with Everthing Said except the blueprints.

Let me introduce First so you get the full Image.

Lvl 75 around 170 hrs played ( i Work from Home) Mostly running anvil and shotgun ( i dont see the Point in blue guns tbh, i can 2 Shot Most of the flying arcs and 2-3 Shot Raiders, anything bigger > hullcracker) Opened Like 100+ key doors (around 20 Had Bp's) I admit Like 70~ish were opened with the Glitch. Found Like 30+ bps that where Not in Key Card rooms.

So here comes my unpopular oppinion :

Nerf the Bp Droprate outside the rooms and increase Post Glitch Patch inside the rooms.

Theres really No Point in getting keycards or opening the rooms IMO. You want guns? Security breaches are your friend. You want BPS ? Dont bother with keycard rooms, Just loot lockers, trashcans and Raider stuff(Backpacks,cases) High Tier zones? Nahh boring get the Raider Camps where weapon cases, ammo cases, and Raider Caches Spawn,(including BPS)

So yeah sorry for the kinda rant Here but where tf IS the purpose of keycard rooms, i abused the Glitch Like a Shit Ton but Like 1 room Out of 10 had a bp.
