Sounds Both Good and Bad, I think it should be like this.
MORE Guards, With Enclave CA and APA (Seriously, they have Enclave CA, but never bothered to use it?) I think about 10-20, if too much, Less than 5 Person team will be rekt'd, plus, One Power Armor, 10 Dudes? Yeah, Bloodbath.
A Advanced Power Armor Locker, But Its inside a 'OFF LIMIT' Area In the Base, I mean, If you're a member of Enclave, you can just waltz in!
And Make the locker spawns after 24 Hours.
